Limits and behavior
Flat scalar values only (strings, finite numbers, booleans or null). Union of object keys supplies columns. Numbers require at most 15 significant digits and safe integers; use strings for exact larger values. Nested objects and dangerous keys are rejected. Local processing. Maximum 10 MB per file, 25 MB total; expanded ZIP contents at most 50 MB and 2,000 entries. Spreadsheet limit: 10,000 cells and 2,000 rows per sheet. Macros are never executed. Originals are unchanged. Cancellation stops active PDF renders and discards stale results; a synchronous library step finishes before the browser can handle cancellation.
Create an Excel workbook from JSON records
Convert JSON object records into columns and rows for a real XLSX file that opens in spreadsheet software.
Can nested JSON structures always fit naturally into spreadsheet cells?
No. Nested objects and arrays may require preprocessing or careful review before tabular use.
