Fixed-Width to CSV

Convert fixed-width text into CSV.

Legacy fixed-width to CSV

Old systems export columns by character position, not delimiters. Define the column widths and this slices each line into fields and emits proper CSV, ready for a modern spreadsheet.

It rescues data from mainframe and banking exports that predate delimited formats, turning rigid column positions into a CSV any modern tool can read.

Get the widths right

Columns are split by the positions you set, so double-check alignment on a sample row. The conversion happens in your browser, so nothing leaves your device.
