How it Works

01Paste or Upload Your CSV

Paste CSV text or upload a .csv file. Column headers from the first row are used as field names in the fixed-width ASCII table output.

02Set Column Widths & Padding

Choose auto-fit (column width based on the longest value) or specify a fixed character width per column. Padding fills shorter values with spaces to align columns.

03Preview the ASCII Table

A formatted ASCII table preview shows the data with aligned columns, optional border characters (| and -), and a header separator row.

04Copy or Download the Output

Copy the ASCII matrix to clipboard or download as a .txt file — useful for terminal reports, documentation, README tables, and fixed-width file exports.
