JSON to Excel
Convert a JSON array into a formatted Excel file.
Paste an array of objects — keys become column headers (merged across all objects), nested objects are stringified, and the sheet gets a bold header with auto-sized columns.
Frequently asked questions
What if objects have different keys?
The union of all keys becomes the column set; missing values are left as empty cells.
Can I convert a single object?
Yes — a single object becomes a one-row spreadsheet.
