Is my spreadsheet or CSV data uploaded anywhere?

No, every data tool parses and transforms your file locally in your browser. Your data never leaves your device.

What file formats are supported?

CSV and TSV are supported everywhere, some tools also handle direct paste-in of tabular data without needing a file at all.

Is there a row or file size limit?

There's no fixed limit, but very large files (tens of thousands of rows) depend on your device's available memory to process smoothly.
