Pick the right tool for the file

CSVUtility does not replace Excel, Sheets, or Numbers. It replaces the moment those apps choke on a CSV. Each page below says what they still win.

CSVUtility vs Excel
Excel is for workbooks. CSVUtility is for the CSV itself.
Keep Excel for pivots, charts, and sharing an .xlsx. Reach for CSVUtility when the export is the thing you have to clean, search, and send back unchanged.
CSVUtility vs Google Sheets
Sheets is for sharing a table. CSVUtility is for the file on your Mac.
Use Sheets when a few people edit a normal-sized table together. Use CSVUtility when the CSV is too big to import, should not go to Google, or has to stay exactly as text.
CSVUtility vs Numbers
Numbers makes a table look finished. CSVUtility makes a huge CSV usable.
Use Numbers for a budget you want to present. Use CSVUtility for the warehouse export, the broken file, or anything that would freeze a pretty spreadsheet.

Excel is for workbooks. CSVUtility is for the CSV itself.
