This format was developed to support localization workflows where a file is unnecessary. Phrases of that format are populated through an API or a Transifex feature.

The core difference of the FILELESS format is that you can append phrases to the format vs. a file upload that will update the whole phrases found in the uploading file.

FILELESS uses the ICU syntax to represent complex forms for variables, placeholders, and plurals.
Additionally, FILELESS phrases support metadata for:

  • Tags

  • Comments

  • Context

  • Character limit

๐Ÿ“ Note: Currently, the FILELESS format is used by Transifex Native and our Figma Plugin. Phrases from these features are appended on a FILELESS resource in Transifex.

To download phrases from a FILELESS resource, you have two options.

  • Download for use option to download the file in a JSON format.

  • Download as XLIFF. Similarly, you can import translations in a FILELESS format by uploading an XLIFF translation file.
