FORMAT / XLSX
A workbook.
Ready for real work.
Explore XLSX exports for editable spreadsheets, explicit cell types, readable columns, and multiple sheets, with a real sample workbook to inspect.
Design for the person opening the file
XLSX is a good fit when people will sort, inspect, annotate, or continue working in a spreadsheet. A clear header row, sensible column widths, frozen headings, and accurate cell types make the data easier to use. Put context where the recipient can find it without mixing explanatory prose into the table.
Our sample workbook contains the same three fictional customers as the other formats. Inspect the text identifiers and numeric USD values to see the distinction between stored values and presentation.
Keep workbook behavior intentional
Separate input values from calculated cells. Treat customer-supplied text as text, and verify the workbook in the applications your audience uses. Avoid unnecessary complexity, hidden dependencies, and features that change meaning when a workbook is imported elsewhere.
For more detail, read the four-format comparison and the export validation guide.
Use formatting to explain the data
Align amounts consistently, label units, and preserve identifiers exactly. Use styling to establish hierarchy rather than making every cell decorative. A downloadable workbook should remain useful when printed, viewed on a small screen, or imported by another tool.
