Markdown Table Generator

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.

It also works as a table markdown generator for data that already exists. Click Import data, then Use sample CSV to fill in a four-line price list that starts Plan,Price,Seats,Support, choose Load into grid, and set Price and Seats to right-aligned. The output opens with | Plan | Price | Seats | Support | over a delimiter row of | ---- | ----: | ----: | --------- |, and the last row reads | Team | $29 | 25 | Priority |. Untick Padded columns and the same table renders identically from shorter source.

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.

Markdown tables are deliberately limited, and the limits are structural rather than cosmetic. There is no rowspan or colspan, no nested tables, and no block content inside a cell, so a paragraph break or a list has to become a line break or move out of the table entirely. Pipes inside cell content need escaping, since an unescaped one starts a new column and silently shifts every cell after it, which is the single commonest way a table breaks. The alignment row is required, not optional. Column widths in the source have no effect on rendering, so padding cells to line up is purely for whoever reads the raw file, and worth doing anyway if the Markdown will be reviewed as text.
