About these spreadsheet tools

These tools work on spreadsheet files themselves: switching between Excel workbooks and CSV, splitting a CSV that is too big for an app’s import limit, combining several exports into one file, turning a CSV into JSON or back, and cleaning up separators, character encodings, extra spaces and empty rows.
