CSV to ASCII Table

ASCII · Unicode box · rounded · heavy · Markdown · simple · numbers right-aligned

Render a CSV as a properly aligned text table — for a README, a code comment, a commit message, a terminal paste, or a Slack snippet. Column widths are measured from the content, numeric columns are right-aligned so digits line up, and you can cap the width of long cells.

How to make a text table

Paste the CSV or drop a file.
Pick a style — ASCII for maximum compatibility, Unicode box for looks, Markdown for GitHub and docs.
Set max cell width to truncate long values with an ellipsis so the table stays readable.
Copy the result. It only looks right in a monospaced context, which is where these belong.

Which style where

ASCII — plain +, -, and |. Safe anywhere: code comments, logs, email, ancient terminals.
Unicode box / rounded / heavy — box-drawing characters for a cleaner look. Needs a UTF-8 environment and a font with the glyphs; most modern terminals and editors are fine.
Markdown — renders as a real table on GitHub, GitLab, and most wikis, with alignment colons derived from the numeric columns.
Simple — columns separated by spaces with a dashed underline. Minimal noise, and easy to parse again with Fixed width to CSV.

Why alignment matters more than borders

The point of a text table is scanning a column vertically. Right-aligning numbers puts the units, tens, and hundreds in the same place so magnitude differences are visible at a glance — left-aligned numbers hide them. Detection is per column: a column is right-aligned only when every non-empty value parses as a number, so a mixed column with a stray N/A stays left-aligned rather than looking broken.

FAQ

Why is my table misaligned when I paste it somewhere?

The destination isn't using a monospaced font. Wrap it in a code block (triple backticks in Markdown or Slack) and it will line up.

Do wide characters line up?

Widths are counted in characters, so CJK and emoji — which occupy two cells in a terminal — will look slightly wide. Latin text is exact.

Can I go back from a text table to CSV?

For the simple and fixed-width styles, yes — Fixed width to CSV detects the columns. For bordered styles, strip the border characters first with Find & replace.
