Markdown Table Generator turns a spreadsheet-style grid into a valid GitHub Flavored Markdown table. Type into cells, add or delete rows and columns, choose left, center, or right alignment per column, and copy the finished Markdown into a README, a pull request description, documentation, a Jira ticket, or a static-site post.
Writing table syntax by hand is where Markdown stops being pleasant. Pipes have to line up mentally, the delimiter row needs one entry per column, alignment is encoded with colons that are easy to put on the wrong side, and any literal pipe inside your data breaks the row. This tool handles all of that: it escapes pipes, converts newlines inside a cell into a line break tag, pads every column so the raw source stays readable in a monospace editor, and always emits the delimiter row your renderer needs.
Data rarely starts in Markdown, so import is built in. Paste CSV, tab-separated text copied straight out of Excel, Google Sheets, or Numbers, semicolon-separated exports from European locales, or an existing Markdown table you want to restructure — the delimiter is detected automatically and quoted fields are parsed the RFC 4180 way. Everything runs in your browser, so spreadsheets with internal numbers never leave your device.
Type directly into the grid, or open the Import panel and paste CSV, tab-separated data from a spreadsheet, or an existing Markdown table. Click Load Sample to see a filled example.
Add or remove rows and columns with the buttons around the grid, move a row up or down, or transpose the whole table if your data was pasted column-wise.
Pick left, center, or right alignment for each column from its header control. Toggle padded output for readable source, outer pipes for the conventional GFM style, and the header row on or off.
Copy the generated Markdown to your clipboard, switch the output tab to HTML or CSV if you need a different format, or download it as a .md file.
Edit cells in a real grid with add, delete, move, and transpose controls instead of counting pipe characters by hand
Delimiter detection handles commas, tabs, semicolons, and pipes, and quoted fields containing commas or newlines are parsed correctly
Paste a Markdown table you already have and it loads back into the grid with its column alignments preserved, ready to edit
Left, center, and right alignment are written into the delimiter row with the correct colon placement for GitHub, GitLab, and most Markdown renderers
