Frequently asked questions

Will the CSV open correctly with accented characters?

Yes. The output is standard CSV; if Excel shows garbled characters, select UTF-8 encoding when opening the file.

What about cells that contain a comma?

The tool automatically wraps that cell in double quotes, per the standard CSV format.
