About this tool
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.
Example. Typing Name and Age into the header cells emits a GitHub-flavored table that starts with a header row Name and Age and a separator row of dashes.
Limit. The grid refuses to grow past 20 columns or 100 rows including the header.
