CSV Encoding Fixer

Open a CSV that shows up as garbage, detect its encoding (GBK, Big5, Shift-JIS, Latin-1) and export clean UTF-8 — with a BOM for Excel.

File to repair

Everything runs in your browser — the file is never uploaded. Read the warning: characters already lost cannot be recovered.

Open a file (or paste text) on the left to see how it decodes.

How it works

  1. 1.Import an Excel, CSV, TSV or JSON file, or paste the table. It is parsed on your own device.
  2. 2.Pick the columns to show: one category axis and up to three values.
  3. 3.Generate once, then keep tweaking — chart type, aggregation, sorting and theme update instantly.
  4. 4.Download an image, or publish the result as an encrypted link that expires on its own.
