What changes between String Catalog and Markdown
- String Catalog holds every language in one file, so the converter writes one Markdown file per language found in the source.
Convert and translate in one place
If you need the Markdown file in more languages, the fastest route is a free SimpleLocalize project: import the String Catalog file, add languages, run auto-translation with DeepL, Google Translate, OpenAI, Claude or Gemini, and download the result as Markdown. The CLI does the same from CI with upload and download commands, so the conversion becomes part of your build. See also translating String Catalog files.
Frequently asked questions
Is the converter free?
Yes. There is no signup and no limit on the number of conversions beyond a few requests per second.
Are my files stored?
No. The file is parsed in memory, converted and returned in the same request. Nothing is written to disk or a database.
What about plurals and placeholders?
Plural forms are normalized to ICU message syntax and written back in the native form of Markdown. Placeholders are kept, and Apple and Android specific syntax is translated between platforms. Read more in the pluralization guide.
