About ASCII Table Generator
Build beautiful ASCII art tables with an interactive spreadsheet-like editor. Add rows and columns, edit cells inline, and choose from 5 border styles: simple (+---+), rounded corners (╭───╮), double lines (╔═══╗), GitHub Markdown pipe tables, and minimal spacing. Copy the result with one click. Perfect for README files, CLI tool output, pull request descriptions, wiki pages, and documentation.
All processing happens entirely in your browser using modern web APIs. Nothing is uploaded to our servers — your data stays local and private. Free to use forever, with a Pro plan for power users who want an ad-free experience and API access.
Common use cases
- Creating comparison tables in README.md files for GitHub or GitLab
- Generating formatted tables for command-line tool help text and documentation
- Building data tables for pull request descriptions and issue comments
- Creating visual tables for blog posts on platforms that don't support HTML
- Displaying structured data in terminal output or shell scripts
How it works
The interactive editor maintains a 2D array of cell values. When you generate the table, the tool calculates the maximum content width for each column, then builds the output line by line: top border, header row, separator, data rows, bottom border. Unicode box-drawing characters (─, │, ├, ┤, ╭, ╮, ╔, ╗, etc.) are used for styled borders.
