About this Tool
Use this JSON to Excel Converter to create a spreadsheet file from JSON data. Arrays of objects can become worksheet rows, object keys become columns, and nested fields can be flattened with configurable path notation. The output is intended for table values and review workflows, not for preserving executable workbook behavior or advanced formatting.
Examples
- [ { "id": 1, "name": "Marta", "team": "Sales", "quota": 12500 }, { "id": 2, "name": "Jon", "team": "Success", "quota": 9800 }, { "id": 3, "name": "Lea", "team": "Sales", "quota": 14100 } ]
Frequently Asked Questions
Is my JSON data uploaded to a server?
No. The tool parses, transforms, previews, and exports data locally in your browser without uploading your input.
How are nested JSON values handled?
Objects can be flattened with configurable path notation. Arrays work best when they contain row-like objects; deeply mixed arrays may need manual review before conversion.
Are Excel macros or formulas executed?
No. Spreadsheet tools read and write cell values only. Macros are not run, and a complete formula calculation engine is not promised.
Will formatting, charts, or workbook features be preserved?
Not reliably. These tools focus on table data. Charts, formulas, comments, complex formatting, and advanced workbook features may be ignored or simplified.
What file sizes are practical in the browser?
Small and medium tables are the best fit. Very large files can use a lot of memory because parsing, previews, and exported results all live inside the browser tab.
