What is a .xlsx file?
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
XLSX is the default Microsoft Excel format, an Office Open XML spreadsheet stored as a ZIP archive containing worksheet XML, shared strings, styles, and formulas. It supports multiple sheets, cell formatting, charts, and calculated values. It is the standard for editable tabular workbooks.
How to use a .xlsx file
Use an example XLSX to test spreadsheet parsing, formula and multi-sheet handling, shared-string extraction, and pipelines that read or generate Excel workbooks.

- Pine Assembly Workshop: Shipment export workbookShipment export workbook for Pine Assembly Workshop. One worksheet named Shipments with a header row and 16 data rows carrying the same values as shipments-export.csv. Weights are stored as text, so the trailing zero in a figure such as 24.400 survives the round trip instead of being displayed as a shorter number.
