CSV to Fixed Width

Turn a spreadsheet into a fixed-width text file: set the column widths, alignment, letter case and optional ASCII borders.

Your data never leaves this browser

The file is parsed, previewed and charted on your own device. Nothing is uploaded — not even a sample. Close the tab and the data is gone.

Or paste table text

How it works

  1. 1.Import your table: paste CSV or Excel data, or pick a file.
  2. 2.Choose where the widths come from: fitted to the content (then adjust the extra space), or typed in per column.
  3. 3.Pick the alignment and letter case, add a separator character if the target system wants one, and switch on ASCII borders when a human has to check the result.
  4. 4.Create the text file, check the column offsets in the preview, then download the .txt.
