- you need high compatibility with Excel 2007+ formats including charts and styles
- you need to process very large worksheets efficiently via streaming

## When to avoid
- you work in another language (ports exist for C#, JavaScript, Python)
- you need to edit legacy .xls binary files
- you need a GUI spreadsheet application
