ASCII Table Formatter

Turn CSV or tab-separated text into an aligned plain-text, Markdown or box-drawing table.

An ASCII table formatter aligns delimited rows into a readable fixed-width table. Paste CSV, tab or pipe separated data and get box-drawing, ASCII, Markdown or plain aligned output, with numeric columns right-aligned automatically so figures line up on the decimal.

Frequently asked questions

Why do my columns misalign after formatting?

Almost always a proportional font. Fixed-width alignment only holds in a monospace font, where every character occupies the same width. Wide CJK characters also break it, because they occupy two cells rather than one.

When should I use a Markdown table instead?

Whenever the output will be rendered — GitHub, a README, documentation. Markdown lets the renderer size the columns, which adapts to the screen. Box-drawing tables are for terminals and plain-text files, where nothing will lay them out for you.
