DEVELOPER TOOL
Markdown Table Generator
Turn CSV or spreadsheet data into a ready-to-paste Markdown table.
About this tool
Paste data copied from a spreadsheet (tab-separated) or CSV and instantly get a GitHub-flavored Markdown table, ready to drop into a README, pull request, or wiki page. The first row is treated as the header, and column widths are automatically padded to line up neatly.
Everything runs locally in your browser — nothing is uploaded.
Frequently asked questions
- Does this work with data copied straight from Excel or Google Sheets?
- Yes — pasting a selection from a spreadsheet produces tab-separated values, which this tool detects automatically, alongside comma-separated CSV.
- What if a cell contains a pipe character (|)?
- Pipes are automatically escaped as
\|so they don't break the table structure when rendered as Markdown. - Can I align columns?
- Yes — choose Left, Center, or Right to add Markdown's alignment markers (
:--,:-:,--:) to the header separator row, or leave it as Default for no explicit alignment.
