About this tool
Use csv data profiler without uploading files
Inspect column types, unique values, empty cells, ranges, and duplicate rows. CSV Data Profiler runs in the current browser session, giving you a direct result without sending the source to a Filemazing processing server.
Processing takes place in your browser tab. Temporary working data is released when you leave or reload the page.
Three steps
- Provide the source values or files for CSV Data Profiler.
- Run the local inspection and review every reported field or difference.
- Copy the findings or use them to decide the next processing step.
