Fixed Width to CSV

Turn COBOL, bank or mainframe exports into CSV or Excel: set the column widths (or detect them) and the fixed-width text becomes a real table.

Fixed-width text

Everything runs in your browser — the file is never uploaded. Only characters are cut at the widths you set; nothing is reformatted.

Paste fixed-width text on the left, set the widths and press Convert.

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.
