Frequently asked questions
What happens to values that contain commas?
They are wrapped in double quotes, so each value stays in its own column when the CSV is opened.
Can I paste straight from Excel or Google Sheets?
Yes. Cells copied from a spreadsheet are separated by tabs, which is exactly what this tool expects.
Why does it say no tabs were found?
The text you pasted has no tab characters, so it is probably already CSV or plain text.
Is my text uploaded to a server?
No. This tool runs entirely in your browser, so what you paste never leaves your device.
