The markdown table generator works like this: it turns pasted CSV, TSV or spreadsheet-like rows into GitHub-flavored Markdown tables with alignment options. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

Frequently asked questions
How do I align columns left/center/right?
Use the per-column alignment picker; it emits the :---: style markers GitHub renders.
What input formats can be pasted?
CSV, TSV, or spreadsheet-style rows (cells separated by tabs or consistent delimiters) - the first row becomes the header by default, with a toggle when it should not.
How do I align columns in the output?
Per-column alignment options emit the GitHub-flavoured :--- / :---: / ---: markers, which render as left, centre and right alignment on every Markdown platform that supports tables.
