About XLSX to CSV
Convert an Excel (.xlsx) workbook to one or more CSV files, one per worksheet. Formulas are evaluated to their current values; formatting is dropped. Perfect for feeding spreadsheets into pipelines that expect plain CSV.
Frequently asked questions
What if cells contain commas or newlines?
The CSV is RFC 4180 compliant: fields with commas, quotes, or newlines are wrapped in double quotes with quotes escaped.
How are dates exported?
ISO 8601 (YYYY-MM-DD) by default. Cells formatted as text export verbatim.
