XLS Padlock provides localization support for your protected workbooks, allowing you to display all interface text—such as dialog captions and messages—in the language of your choice.
You can configure localization for your protected workbook app here:

XLS Padlock loads all UI text from translation files with a .sil extension. By default, it uses the English.sil file located in the XLS Padlock installation folder.
XLS Padlock includes several pre-made language files, which are automatically loaded into the dropdown list at startup. You can choose an existing language file, such as German or French, directly from this list.
The following languages are currently available: English, French, Spanish, German, Portuguese (Brazil), Dutch, Slovenian, Croatian, and Arabic.

If you need a language that is not on the list, please contact us.
Editing Translation Files
Translation files are plain text files that must be saved with UTF-8 encoding. You can edit them with any text editor, such as Notepad or Notepad++.
How to define a language for your workbook application #
- To select a translation file, you can choose one from the dropdown list, click Browse to locate a file, or enter the full path manually.
- To customize a translation file, click Edit. The selected
.silfile will open in your default text editor.
If no language file is specified, the default English file is used. Since modifying files in the installation directory often requires administrative rights, we recommend that you first copy the default language file to a new location, modify the copy, and then specify the path to your new file.
Warning
The selected translation file must be accessible at its specified path when you compile your application. XLS Padlock reads this file during the build process.
