What is a XLSX file?
XLSX is Excel's native format: multiple sheets, formulas, charts, formatting and proper data types in one file. Google Sheets, LibreOffice and Numbers all open it too.
What is a CSV file?
CSV is the lingua franca of tabular data: plain-text rows of comma-separated values that every spreadsheet, database and programming language can read. It holds exactly one sheet, with no formulas or formatting.
Why convert XLSX to CSV?
XLSX needs spreadsheet software and doesn't diff, script or import cleanly, so data pipelines prefer plainer formats. CSV is plain text that every tool ever written can import — the safest way to move tabular data around.
