Before you begin

Uses standard JSON syntax; comments and trailing commas are not accepted.

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.
