A VSCode extension to keep XLIFF translation files in sync with an automatically generated base-XLIFF file.
Note that there is also an "XLIFF Sync" PowerShell module!
The "XLIFF Sync" extension for Visual Studio Code can help you work more efficiently with XLIFF translation files in various ways.
It is specifically targeted at easing translation of extensions for Microsoft Dynamics 365 Business Central, by allowing you to more easily keep .xlf translation files of your extensions in sync with the .g.xlf files that are automatically generated by the AL Language extension.
However, it can also be used in combination with other software projects that use XLIFF translation files for translation, supporting both XLIFF 1.2 and XLIFF 2.0.
Apart from synchronizing trans-units from a base-XLIFF file, this extension contributes various other features, including commands to check for missing translations, detect problems in translations and import translations from external XLIFF files.

- Search and highlight missing translations in an open XLIFF file.
- Run technical validations to check for problems in the translations of target XLIFF files.
- Import/Copy translations for matching sources from external XLIFF files to target XLIFF files.
- Support for XLIFF 1.2 and 2.0
- Convert between XLIFF 1.2 and 2.0 format.
| Command | Explanation |
|---|---|
| XLIFF: Create New Target File(s) | Create one or more new target XLIFF files from the base-XLIFF file. |
| XLIFF: Synchronize to Single File | Merge new trans-units from base-XLIFF file into a manually specified target XLIFF file. |
| XLIFF: Synchronize Translation Units | Merge new trans-units from base-XLIFF file into all other XLIFF files in the open project folder. |
| XLIFF: Check for Missing Translations | Checks if there are any missing translations in the target XLIFF files in the open project folder. For each file with missing translations, an informational message will be shown (with a button to open the file externally). |
| XLIFF: Check for Need Work Translations | Checks if there are translations that need work in the target XLIFF files in the open project folder. For example, the source text contains placeholders (e.g., "%1" or "{0}") while the translation does not. Translations with problems will be tagged with needs-adaptation and an "XLIFF Sync" note will be added to the trans-unit node. For each file with translations that need work, an informational message will be shown (with a button to open the file externally). |
| XLIFF: Next Missing Translation | In an XLIFF file that is currently opened in the active editor, search for the next missing translation. |
| XLIFF: Next Needs Work Translation | In an XLIFF file that is currently opened in the active editor, search for the next translation tagged as needs-adaptation. |
| XLIFF: Import Translations from File(s) | Import/Copy translations from external XLIFF files to trans-units with matching sources of target XLIFF files with the same target-language. |

The extension will try to find corresponding trans-units and translations within an existing file as follows:
- Finding trans-units:
- By Id
- By XLIFF Generator Note & Source (enabled by default, configurable with
xliffSync.findByXliffGeneratorNoteAndSource)- By XLIFF Generator Note & Developer Note (enabled by default, configurable with
xliffSync.findByXliffGeneratorAndDeveloperNote)- By XLIFF Generator Note (enabled by default, configurable with
xliffSync.findByXliffGeneratorNote)
- Finding translations:
- By Source & Developer Note (disabled by default, configurable with
xliffSync.findBySourceAndDeveloperNote)- By Source (disabled by default, configurable with
xliffSync.findBySource)
- Initial translation:
- Parse from Developer Note (disabled by default, configurable with
xliffSync.parseFromDeveloperNote)- Copy from Source, if applicable/configured for target language (disabled by default, configurable with
xliffSync.copyFromSourceFor...)
If no trans-unit or translation is found, the unit is added and its target node is tagged with state="needs-translation".
- F1 or Ctrl/Cmd + Shift + P to open the command palette
- XLIFF: Create New Target File(s)
This command will let you create one or more new target files, letting you choose from a set of RFC 4646 or RFC 5646 language tags depending on the XLIFF file type (i.e., xlf or xlf2).
The new file is automatically synced with the base file; if it is not known you will be prompted to specify the file to use as the base file first.
More detailed instruction: Create New Target Files
- F1 or Ctrl/Cmd + Shift + P to open the command palette
- XLIFF: Synchronize to Single File
- Alt + X, S (default shortcut)
By default, the extension expects the base-XLIFF file to end with .g.xlf.
If no matching file is found, you are prompted to identify the base file.
This setting will be saved for future use.
If the extension is invoked from a localization file, that file will be updated, otherwise the extension will prompt you for the file to update.
You can also use this command to create a new XLIFF file for a language. For this, choose the "New File..." option and choose the language tag for the new target language.
- F1 or Ctrl/Cmd + Shift + P to open the command palette
- XLIFF: Synchronize Translation Units
NOTE: This command will merge new translations into all XLIFF files in your workspace folder (with, obviously, excluding the base-XLIFF file itself).
- Alt + X, M (default shortcut)
- Right-click on a file with the .xlf extension.
- Select: Synchronize Translation Units
If you select the base-XLIFF file, then translation units will be synced to all other XLIFF files in the workspace. If you select any other XLIFF file, then translation units will be synced from the base-XLIFF file to the selected file.
Here's a small demo:
More detailed instruction: Synchronize Translation Files
- F1 or Ctrl/Cmd + Shift + P to open the command palette
- XLIFF: Check for Missing Translations
This will check all XLIFF files in the workspace and notify about any missing translations in the files. You also have the option to open files with missing translations with your default XLIFF editor using the Open Externally button from the informational message.
More detailed instruction: Check Translation Files
- F1 or Ctrl/Cmd + Shift + P to open the command palette
- XLIFF: Check for Need Work Translations
This will run technical validation/checks for all XLIFF files in the workspace and notify about any translations that need work in the files. You also have the option to open files containing problems with your default XLIFF editor using the Open Externally button from the informational message.
The target node of the trans-units containing problems will be tagged with state="needs-adaptation".
Additionally, a note will be added to the trans-unit to explain which problem was detected.
When you run the command again after resolving the issue, then this note will be automatically removed.
You can configure the checks that need to be run with the xliffSync.needWorkTranslationRules setting.
The currently implemented checks are the following:
| Rule ID | Check | Trigger | Example |
|---|---|---|---|
ConsecutiveSpacesConsistent |
'Consecutive space'-occurrences are not matching. | N.A. | The source text includes 3 consecutive spaces, the translation text includes 2 consecutive spaces. |
ConsecutiveSpacesExist |
Source or translation text contain consecutive spaces. | N.A. | The source text includes 2 consecutive spaces, e.g., Hello World |
OptionMemberCount |
Number of options in caption are not matching. | Xliff Generator note with Property OptionCaption or Property PromotedActionCategories. |
The source text includes 3 options, A,B,C , but the translation text includes 4 options, A,B,C,D. |
OptionLeadingSpaces |
Number of leading spaces in options are not matching. | Xliff Generator note with Property OptionCaption or Property PromotedActionCategories. |
The source text includes a space, A, B , but the translation text does not, A,B. |
Placeholders |
Placeholders of source and translation are not matching. | Source/Translation text includes placeholders of the form {0} or %1 or #1. |
The source text includes placeholders %1 %2 , but the translation text only includes %1. |
PlaceholdersDevNote |
Placeholders are not explained in the Developer note. | Source text includes placeholders of the form {0} or %1 or #1. |
The source text includes placeholders %1 %2 , but the Developer note is empty and so does not contain the placeholders. |
SourceEqualsTarget |
Source and translation are not the same, even though source-language = target-language for the .xlf file. | The source-language is the same as the target-language for the .xlf file. | The source text is 'A', but the translation text is 'B'. The source-language and target-language are both 'en-US'. |
Note: You may want to use rule SourceEqualsTarget in combination with setting xliffSync.copyFromSourceForSameLanguage set to true.
More detailed instruction: Check Translation Files
- F1 or CMD + Shift + P to open the command palette
- XLIFF: Next Missing Translation
- Alt + X, N (default shortcut)
Missing translations are tagged and highlighted. You can use the extension to navigate between missing translations. On a Macbook Pro, this command appears on the touchbar within XLIFF files.
- F1 or CMD + Shift + P to open the command palette
- XLIFF: Next Needs Work Translation
- Alt + X, W (default shortcut)
Translations that need work are tagged and highlighted. You can use this command to navigate between translations that need work. On a Macbook Pro, this command appears on the touchbar within XLIFF files.
- F1 or Ctrl/Cmd + Shift + P to open the command palette
- XLIFF: Import Translations from File(s)
This will open a file dialog in which you can select one or more XLIFF files (.xlf or .xlf2). The command will copy translations from the selected files to trans-units in the XLIFF files in your project folder with the same target-language for matching sources. It will try first to merge translations for trans-units with a matching combination of source-text and Developer note, and only after that try to merge translations to trans-units with matching source-text. That way you could utilize the Developer note to have the import perform a more precise merge of the translations (e.g., based on tags in the Developer notes).
More detailed instruction: Import Translations from Files
- Automatically inserting new groups into target files is not implemented.
- The NAV2018 XLIFF generator creates Xliff Generator Notes without any identifiers, therefore it is recommended to change the
xliffSync.findBy...settings to not synchronize trans-units based on Xliff Generator notes. - Files larger than 50 MB cannot be processed at the moment. For now, please use the "XLIFF Sync" PowerShell module instead.
