- Excel holds every language in one file, so the converter writes one iOS .strings file per language found in the source.
- Plural messages cannot be expressed in .strings files. Convert plurals to .stringsdict or a String Catalog instead.

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 iOS .strings. Placeholders are kept, and Apple and Android specific syntax is translated between platforms. Read more in the pluralization guide.
