Free tools
日本語版はこちらSmall, single-purpose tools for localization files and garbled text. Every one runs in your browser — nothing is uploaded, and none of them need an account.
Reading on these problems is in the blog
- Mojibake decoder
Paste garbled text and get the original back. Tries every common encoding pair — UTF-8, Shift_JIS, EUC-JP, Windows-1252, GBK, Big5, EUC-KR, Cyrillic — in your browser. Nothing is uploaded.
- Free localization file checker
Check a game localization CSV for broken placeholders, untranslated strings, duplicate keys, and encoding problems. Runs entirely in your browser — no upload, no account.
- Placeholder mismatch checker
Find placeholders that were dropped, renamed, or retyped in fullwidth characters during translation. Runs in your browser — no upload, no account.
- Mojibake and encoding checker
Find out which encoding your localization CSV really is — UTF-8, UTF-8 with BOM, UTF-16, or Shift_JIS — and catch garbled Japanese before it ships. Runs in your browser.
- Untranslated string finder
Find rows that were never translated: empty targets and targets still identical to the source. Runs in your browser — no upload, no account.
