Get CSV for a database import
Most import tools want CSV, not Excel. Convert here and feed the result straight into MySQL, Postgres or a data pipeline.
Export every sheet at once
Multi-sheet workbook? Download all sheets as a zip of CSVs in a single click instead of saving each one by hand.
Feed data to a script
CSV is trivial to parse in Python, R or shell. Convert an .xlsx report into CSV your script can read.
Share data without Excel
CSV opens anywhere. Convert so the recipient doesn't need Microsoft Excel to read your data.
