How to use this tool
Choose a CSV file to check its first row and report duplicate or blank headings.
Before you begin
Works with standard CSV/TSV and does not check import rules inside your destination system.
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.
