Batch Processing Export and Import in XML format. Passolo 2022 Team 5 Edition 22.0.254.0

Julie Latta — Thu, 16 Apr 2026 12:14:57 GMT

I have the Passolo 2022 Team 5 Edition 22.0.254.0 software installed and I am attempting to script an export in XML format. I am finding that I don't have the ability to script this for various reasons. For instance the COM class that I have access to does not have the ability to open the project. Can you tell me if there is something else I have to purchase in order to be able to script or batch the export/import of my project? An example of the attempt:in Powershell:

# Create Passolo COM object

$passolo = New-Object -ComObject "Passolo.Application.22"

$passolo | Get-Member

$passolo.Visible = $false

# Open the project via Documents

$passolo.Documents.Open("D:\Work3\User_Interface\PassoloProjects\Core.2601\Core.2601 - Copy.lpu")

Received this error:

I am able to do this manually through the desktop application. My question is do I have to purchase something else in order to be able to perform an export and import in batch mode?

How to change the virtual folder path?

Gavin Lambert — Tue, 17 Feb 2026 04:06:37 GMT

I am currently using Passolo 2022 22.0.254.0. Once I have obtained an IPslSourceList, I can read the current Virtual Folder Path via the VirtualFolderPath property, but attempts to write to this property fail:

ERROR: System.Runtime.InteropServices.COMException (0x0000F18D): Unable to write read-only property.
at System.RuntimeType.InvokeMember(String name, BindingFlags bindingFlags, Binder binder, Object target, Object[] providedArgs, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParams)
at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Object[] aArgs, Boolean[] aArgsIsByRef, Int32[] aArgsWrapperTypes, Type[] aArgsTypes, Type retType)
at PassoloU.IPslSourceList.set_VirtualFolderPath(String)

Is this a bug? Writes to other properties succeed. If this is intended, is there an alternative method for moving a source list to a different virtual folder?

RE: How to change the virtual folder path?

Adrian Maniu — Thu, 26 Feb 2026 13:36:53 GMT

Hi Gavin Lambert , currently the Virtual folder path is read only and cannot be changed.

We have a request CRQ-43623 for the dev team to implement a way to change the Virtual Folder Path and I hope it will be included in the near future.

RE: How to set the "Filter settings for translation list" example "Untranslated"

Achim Herrmann — Fri, 13 Feb 2026 17:39:13 GMT

As Adrian mentioned, switching the filter is a function that can only be done by users from the UI. You can potentionally circumvent the problem by just sending some keys after you opened all the translation lists by macro. This will then look like

    SendKeys "^L",1
    SendKeys "%S",1
    SendKeys "{Tab}{Tab} ",1
    SendKeys "{Enter}"

How to set the "Filter settings for translation list" example "Untranslated"

Daniel Masson — Wed, 04 Feb 2026 15:09:26 GMT

Hi,

My goal is to open the translists and see only the "Untranslated" string.

How I can set the "Filter" before the Open.

For j = 1 To prj.TransLists.Count

prj.TransLists.Item(j).Open
END IF 

Thanks for your help 
Daniel

Hi Daniel Masson , maybe you can check if the
https://docs.rws.com/en-US/passolo-automation-957276/passoloapp-onfiltertransstring-456122
helps you.

Also please confirm what is the end goal of this. You can just change the filter from the UI:

Automating just the change of the filter seems to not help too much.

RE: Macro cannot read right string ID

Adrian Maniu — Fri, 16 Jan 2026 12:15:05 GMT

Hello,

This is explained in the Automation help:

https://docs.rws.com/en-US/passolo-automation-881527/psltransstring.id-465941

The ID of strings from resource type StringTable is a combination of the resource id and the item id. To calculate the string id use this formula:

Dim s As PslSourceString
...
Dim id as Long
id = s.ID
If s.Resource.Type = "StringList" Then
  id = 16 * (s.Resource.ID - 1) + s.ID
Else
  id = s.ID
End If

In your example the output works fine with:

PSL.Output("ID: " & 16 * (trnStr.Resource.ID - 1) + trnStr.ID)

I hope this helps.

Thanks,

Adrian Maniu

RE: Passolo MT Workflow – Resetting MT-Only Strings After Glossary Update

Achim Herrmann — Tue, 26 Aug 2025 13:36:39 GMT

Without analyzing the code in detail here, I would say that the error message should be heeded, and the error can be fixed that way. So use Dim tl as PslTransList .

Passolo MT Workflow – Resetting MT-Only Strings After Glossary Update

Franz-Josef Knelangen — Fri, 22 Aug 2025 12:07:43 GMT

Hi everyone,

I'm working with a localization workflow that integrates DeepL via Tralotec's API, which includes a glossary feature. In our setup, machine translation is applied only to segments not already translated by humans, and glossary terms are crucial for maintaining consistency.

Here's the challenge:
Whenever a new term is added to the glossary, I need to ensure that all strings previously translated only by MT (i.e., without human post-editing) and containing that term are reset to "untranslated." This way, the next MT pass will correctly apply the updated glossary term.

I've attempted to implement this logic in a macro, but unfortunately, the code isn't working as expected. Before diving deeper into debugging, I’d like to share the concept and code with the group to see if anyone has tackled a similar issue or has suggestions. This is the code:

' Dieses Makro setzt alle Segmente auf "Untranslated",
' die mit DeepL Pro MT übersetzt wurden UND einen Glossarbegriff enthalten.

Sub Main()

' Glossarbegriffe manuell eintragen (deutsche Quellbegriffe)
Dim glossaryTerms
glossaryTerms = Array( _
"ProduktnameXY", _
"FachbegriffZ", _
"MarkennameABC", _
"Abschattierung", _
"Absteckung" _
)

' Durchlaufe alle TranslationLists im aktiven Projekt
Dim tl
For Each tl In ActiveProject.TranslationLists

Dim str
For Each str In tl.Strings

If str.Property("Origin") = "DeepL Pro Machine Translation" Then
For Each term In glossaryTerms
If InStr(str.SourceText, term) > 0 Then
str.Status = TranslationStatus.Untranslated
Exit For
End If
Next
End If

Next
Next

End Sub

Has anyone implemented a reliable way to:

Identify MT-only strings that contain newly added glossary terms?
Reset those strings to untranslated so they can be reprocessed with the updated glossary?

Any insights, code snippets, or workflow tips would be greatly appreciated!

Best regards,
Franz-Josef Knelangen

RE: Passolo MT Workflow – Resetting MT-Only Strings After Glossary Update

Franz-Josef Knelangen — Mon, 25 Aug 2025 07:51:49 GMT

Sorry, didn't realize that the comments in the code were in German:

' This macro sets all segments to "Untranslated"
' that were translated with DeepL Pro MT AND contain a glossary term.

Sub Main()

' Enter glossary terms manually (German source terms)
Dim glossaryTerms
glossaryTerms = Array( _
"ProduktnameXY", _
"FachbegriffZ", _
"MarkennameABC", _
"Abschattierung", _
"Absteckung" _
)

' Iterate through all TranslationLists in the active project
Dim tl
For Each tl In ActiveProject.TranslationLists

Dim str
For Each str In tl.Strings

If str.Property("Origin") = "DeepL Pro Machine Translation" Then
 For Each term In glossaryTerms
 If InStr(str.SourceText, term) > 0 Then
 str.Status = TranslationStatus.Untranslated
 Exit For
 End If
 Next
End If

Next
Next

End Sub

Trying to run this code, it stops at "For Each tl In ActiveProject.TranslationLists" with the error msg "Expecting valid data type (f.e. integer)" - my translation from German macro editor in Passolo.

Any clues how to go further?

RE: Passolo SDK 2022 - CPAIProject - Access the String Lists from an CPAIProject

Achim Herrmann — Tue, 29 Jul 2025 11:58:14 GMT

If you want to scan files with BAML resources yourself, you should implement a parser add-in instead of a tools add-in. Then, depending on the Localization.Attribute, you can use the function <token>.SetProperty(enmTokenProperties.StateHidden, 1); to hide entries and exclude them from being shown in the translations lists.

Passolo SDK 2022 - CPAIProject - Access the String Lists from an CPAIProject

Jonathan Gilmore — Tue, 22 Jul 2025 19:01:00 GMT

I'm developing a tools plugin using the Passolo SDK 2022. When the project opens, I receive a CPAIProject object via the OnProjectEvent handler. I'm trying to access the project's String Lists from this object, but CPAIProject appears to have limited functionality compared to the full Passolo API. How can I drill down to the String Lists from this instance?

Jonathan Gilmore — Fri, 25 Jul 2025 13:44:42 GMT

No, I haven’t looked into the Excluded BAML Properties yet. We have some C# code that scans BAML resources to check
if the top-level control includes Localization.Attributes="$Content (NeverLocalize)". If it does, we’d like to hide that BAML resource.

I still need to ask some more questions about the purpose. Maybe it will also be better to discuss this offline by mail.

When you are saying "automatically hiding BAML resources", have you looked into the .NET parser capabilities that would allow you to exclude BAML properties from being parsed into the Passolo. Does that fit your needs?

I previously was in contact with some of your colleagues, so please ask them and send a direct mail to me.

RE: Passolo SDK 2022 - CPAIProject - Access the String Lists from an CPAIProject

Jonathan Gilmore — Wed, 23 Jul 2025 14:39:29 GMT

Hi Achim, I'm working on a tools plugin using the Passolo SDK 2022. My goal is to automatically hide BAML resources in the String List Sources when a project opens, based on a specific criterion. I've registered for the PassoloEvent.OpenProject event, and in the OnProjectEvent handler, I receive a CPAIProject object. However, its functionality seems quite limited compared to the full Passolo API, and I'm unsure how to access the String Lists from it.

RE: Passolo SDK 2022 - CPAIProject - Access the String Lists from an CPAIProject

Achim Herrmann — Wed, 23 Jul 2025 08:52:35 GMT

Passolo SDK and Passolo API (assuming COM) are two completely different functionalities.

The SDK enables the development of add-ins that integrate deeply into the logic of the Passolo software and that uses the interfaces provided by the SDK. This allows features to be implemented (like parsers or dialog editors) that would never be possible with the COM API.

The COM API, on the other hand, is a way to automate the software to a high degree from the outside. This, in turn, allows features and automations to be implemented that would never be possible with the SDK.

Which brings me to the question, what you would like to achieve with the String Lists that you want to access? This information will help me to propose the right approach.

RE: Rename Source/Target Files in a Project

Achim Herrmann — Thu, 10 Jul 2025 09:21:15 GMT

Before starting to analyze your code and reproduce potentials problems, I would like to ask why this should be automated? If the paths have to be changed every quarter, it is probably not really worth the effort of a macro. There is a simple function to adjust the paths in a project.

In the project view, go to the tree view on the left side and open the Folders node. Here you can right-click a sub-folder name and select Change Folder.

This will do the job in some seconds.

Without testing your code, it might be necessary to call PslProject.Close at the end of the code.

Rename Source/Target Files in a Project

Mark Owens — Mon, 07 Jul 2025 11:54:42 GMT

Passolo 2018 Team Edition question.

I have an automation question using C# and COM

I have a bunch of projects which contain files that live in folders with names containing for example 2025Q1.

When I perform a translation outsource at the moment, I manually open each project and change the names of the source folders and target folders to the new year/quarter. e.g., change the project folders from 2025Q1 to 2025Q2

I'd like to automate via a C# COM program but cannot seem to find the way to do it.

I've tried this code, but whilst it does not give an error, neither does it rename the output files in my project. when done.

Can this be done?
Best regards

Mark

In a macro, we use the target language of a string list, namely the language code, e.g., "des" for "German (Switzerland)". For some languages, e.g. "German (Belgium)" there is no language code returned by Passolo. The following code is working fine for "German (Switzerland)" and "German (Austria)" but not for "German (Belgium)". Is there a reason for this? Thanks in advance.

RE: Language.LangCode not set for some target languages in Passolo

Achim Herrmann — Tue, 03 Jun 2025 05:38:34 GMT

Windows Language Codes are quite old, and maybe there is no 3-letter code for some languages. So instead of using the string representation <object>.Language.LangCode I would recommend using the integer representation <object>.Language.LangID and then convert it into the desired string representation using PSL.GetLangCode(). See https://docs.rws.com/en-US/passolo-automation-957276/passoloapp.getlangcode-455934 for more details.

Trados labels exported string from Passolo incorrectly as 100%

Susanne Aldridge — Thu, 06 Mar 2025 16:47:15 GMT

I just upgraded to Trados 2024 and Passolo 2022 (Professional) and have noticed a weird issue. Now, I do not know if this is solely a Passolo issue or a mix of Trados and Passolo, but I assume it is something in the exported SDLXLIFF from Passolo, so I am posting here.

I have received an updated TS string file from our developers. I ran "Create/update string list" and some strings are untranslated because of a change in string IDs or so. Generally, not a big deal, the text is in the TM anyway. Next I export to an SDLXLIFF file to translate in Trados with the settings "Export only untranslated strings" (no other boxes checked). When I open the SDLXLIFF file in Trados, this is what I see:

In 753, 823 and 1175, the green labels indicate 100%, but the text in the translation column is not the right translation. It is not marked as "Translated", but why does it show 100%? This is very confusing and I do not believe it was like that before. It's OK if the text is exported, but it should not be marked as 100%. The little status quick info shows this:

I have looked all over the Passolo settings and cannot find a way to export with the correct score of 0%. What can I do to not have Trados show the wrong score of 100%?

Thanks
Susanne
