About the Custom Pre-Export Processor

This application allows you to process translated strings before writing them into the translated resource file with your own JavaScript code.

Coding

JavaScript code is executed in a sandboxed environment with no access to I/O (file system, network) or external NPM modules.

This app will expose the following variables in the global environment:

• strings - an array of objects containing all strings Crowdin identified as translatable. Please refer to the Developer Portal to learn more about the data structures.
• fileName - the name of the uploaded file;
• projectId - Crowdin project ID;
• languageId - Target language Crowdin ID;
• error - the error message you want to return. If set, the import will be aborted and the error message will be shown to the user;

Edit string properties inside the strings array to introduce changes you need.

Example application

Replace Product with SUPER

for(const string of strings) {
    string.translations[languageId].text = string.translations[languageId].text.replace('Product', 'SUPER!');
}

In JSON files, set the value to empty string for all untranslated strings.

if (fileName.endsWith('.json')) {
    for (const string of strings) {
        if (string.translations[languageId].status == 'untranslated') {
            string.translations[languageId].text = '';
        }
    }
}
