Frequently asked questions

Is my JSON sent anywhere?
No. Parsing and workbook generation both happen locally in your browser.
What JSON shape does it expect?
An array of objects, where each object is a row and its keys become the column headers. An array of arrays also works and is treated as a raw grid.
What happens to nested objects and arrays?
A spreadsheet cell holds one value, so nested structures can't be represented as a grid. Deeply nested JSON is better suited to the JSON to XML or JSON to YAML tools, which keep the hierarchy.
Can I get .xls instead of .xlsx?
No. The output is .xlsx, the current Excel format, which Excel, LibreOffice, Numbers and Google Sheets all open.
