Frequently Asked Questions
What file formats are supported?
You can upload .csv or .tsv files directly. For .xlsx files, paste the data from Excel using Ctrl+V — Excel copies tab-separated values to the clipboard.
Is my data sent to a server?
No. All processing is done in your browser. Your file and data never leave your device.
Can I choose the CSV delimiter?
Yes. You can output as comma-separated (,), semicolon-separated (;), or tab-separated (TSV) format.
How do I open the CSV in Excel?
Save the CSV file and open it in Excel. If columns don't split correctly, use Data → Text to Columns in Excel and choose the appropriate delimiter.
