Frequently asked questions
How do I get CSV out of Excel or Google Sheets?
Select the cells, copy them and paste them here, or save the sheet as CSV and open the file in a text editor. Pasted cells are separated by tabs, so choose Tab.
Why do I see numbers inside quotes?
Turn on 'Turn numbers and true/false into real values'. Without it every value stays text, exactly as it was written.
What if my file uses semicolons?
Choose Semicolon. Many European programs save CSV that way, because the comma is used as the decimal sign.
Is my data uploaded?
No. The conversion runs in your browser, so it is safe for customer lists and other private data.
