Convert CSV to JSON
Turn a translated spreadsheet into nested JSON ready for Laravel JSON files or any JavaScript i18n library.
Frequently asked questions
Does the converter keep :placeholders and plural pipes intact?
Yes. Values are treated as opaque strings, so Laravel placeholders like :name or :count and pipe-separated plural forms come through unchanged.
How is nesting handled?
Nested keys are flattened to dot notation in CSV (cart.empty) and re-expanded into nested structures when converting back.
Is my data uploaded or stored?
The conversion runs on our server but nothing is persisted: files are converted in memory and the response is returned immediately. For PHP input, only string, number and array literals are parsed — code is never executed.
Is there a size limit?
Yes, 200 KB per conversion, which covers even very large lang files. If you need bulk conversion across many locales, import your files into LangSyncer and export any format.
Converting files by hand gets old fast
Import your lang files into LangSyncer once, edit and translate them in a dashboard, and export any format — or skip files entirely with live translations.
