How to use this tool

Choose a CSV or TSV file to detect likely separators and preview the parsed table.

Before you begin

Detection estimates the most consistent separator and may be uncertain for unusual files.

Why keep files local?

The tool reads the input with your browser and processes it on your device. It does not send your file to a Workpico conversion API. If you share a result by copying or downloading it, you control what happens next.
