Frequently asked questions
- What shape should the JSON be?
- An array of objects works best — one row per object. A single object becomes one row, and an array of plain values becomes a single column.
- What about nested data?
- Nested objects are flattened into dotted columns. Arrays of simple values are joined into one cell; anything deeper is written as JSON in the cell.
- Does Cyrillic survive?
- Yes. The .xlsx format stores text as UTF-8, so there is no character set to get wrong.
- Is it a real Excel file?
- Yes, a genuine .xlsx workbook that opens in Excel, LibreOffice and Google Sheets.
