About this tool
Character Encoding Converter bridges the gap between legacy Japanese text encodings and modern UTF-8. It is particularly helpful when dealing with CSV exports, log files, or emails that arrive in Shift_JIS or EUC-JP and need to be shared with tools that expect Unicode.
Features
Bidirectional conversion, automatic detection hints, mojibake recovery that tests multiple encoding paths, file upload support, and downloadable output. The preview area shows the converted text immediately so you can verify correctness.
Use cases
Importing legacy CSV data into modern databases, rescuing garbled email bodies, migrating old documentation into Unicode wikis, and preparing Japanese content for tools that require UTF-8 input.
Why choose this tool
Conversion is performed locally, which protects confidential business documents. The recovery heuristics save hours of guesswork for engineers dealing with legacy systems, and the interface makes it easy to experiment until the output looks right.
FAQ
- Can it repair mojibake?
- Yes. The recovery mode tries common double-encoding combinations and shows the most likely original text.
- Which encodings are supported?
- UTF-8, Shift_JIS, EUC-JP, and ISO-2022-JP are available for both source and target selection.
- Does it handle large files?
- The converter streams input where possible, so multi-megabyte text files can be processed without freezing the browser.
