Spreadsheet
It's a common task to exchange spreadsheet data in comma-separated-value files (CSV). There are various (small) projects for this task:
- spreadsheet package for reading and writing CSV files lazily
- csv package for reading and writing CSV files in a strict way
- bytestring-csv package for reading and writing CSV files (also strict)
