Excel to Markdown Table — Paste and Edit Grid
Build a Markdown table visually: click a cell and type, add rows and columns, set per-column alignment, and copy the ready GFM table.
Result
This page opens the table builder with a tab-separated sample already imported - the same shape you get when you select a range in Excel or Google Sheets and copy it - showing Name, Age and City rows for Alice and Bob.
Copying straight out of a spreadsheet gives you tab-separated cells, not commas, which is exactly what the import box auto-detects here: paste your selection from Excel or Sheets over the sample text and click import, no need to save a .csv file first.
Once imported, the data lands in a real editable grid rather than a converted text blob - click any cell to adjust it, add or remove rows and columns, and the padded Markdown table below stays in sync with every change.
