Why convert XLSX to CSV
XLSX-to-CSV flattens the first worksheet into RFC-friendly rows — merged cells expand to top-left values finance teams must validate.
DSNOOPDOC exports data for ETL, databases, and scripts without Excel installed.
Multi-sheet books export the first sheet — split tabs in Excel when each is a different entity.
Pipeline-friendly CSV
Import into databases and pandas.
No Excel license
Same export on Chromebook and Linux.
Quoted fields
Cells with commas are quoted per CSV conventions.
PDF companion
Use xlsx-to-pdf when auditors need visual layout too.
