What is CSV → Fixed Width?
A CSV→fixed-width formatter: column widths derive from the longest cell, and rows are padded (left or right) to align.
How it works
Column widths are computed from the widest cell in each column, then every cell is padded to that width with the chosen alignment.

Examples
Legacy system exports
Convert CSV to a fixed-width layout with per-column widths — the format many mainframe and legacy import tools still require.
Common mistakes
Truncating long values
Values wider than the column get cut off. The tool flags overflows so you can widen the column first.
Frequently asked questions
How are widths specified?
Per column, in characters — with alignment (left, right, center) and padding options.
Can it convert back to CSV?
Yes — the Fixed-Width to CSV tool reverses the process.
