Get a useful result in seconds. Processing happens on this device.

How to use this tool

Choose a direction, paste the content, then copy or save the converted file.

Before you begin

Converts simple tables. Nested values may be stored as text, and potentially dangerous spreadsheet formulas are escaped.

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.
