This is an interactive tool. Use it at https://promptitin.com/free-tools/csv-to-markdown-table.

## How to use it

1. Paste CSV or spreadsheet cells, open a .csv file, or tap Try an example.
2. Leave the separator on Auto, or pick one if the columns look wrong.
3. Choose whether the first row is the header and whether to line up the columns.
4. Copy the table, or download it as a .md file.

## Tips

- Cells copied from Excel or Google Sheets arrive separated by tabs. Auto picks that up.
- AI models read Markdown tables more reliably than raw CSV, especially with many columns.
- Turn off Line up columns for a smaller table that uses fewer tokens.
- Number columns are aligned right, so totals are easy to scan.

## FAQ

### Can I paste from Excel or Google Sheets?

### What if a cell has a comma in it?

Wrap the cell in double quotes, as CSV files do. Quoted cells keep their commas, quotes and line breaks.

### Where do Markdown tables work?

In ChatGPT, Claude, Gemini, GitHub, Notion, Obsidian and most other tools that read Markdown.

### Is my data uploaded?

No. The table is made in your browser.
