info About this tool
Flatten complex JSON data structure into an easy-to-read Excel table. Supports arrays of objects.

File size: XLSX output size depends on the number of records and fields: typically larger than the source JSON due to Excel format overhead.

Quality: JSON numbers, strings, and booleans are mapped to their Excel equivalents. Null values appear as empty cells.

help FAQ

Does it handle nested objects?

Flat arrays of objects are fully supported. Deeply nested JSON is flattened one level: nested objects become string representations in the cell.

What if my JSON objects have different keys?

All unique keys across all objects are used as column headers. Missing values for a given row appear as empty cells.

Can I convert a single JSON object (not an array)?

A single object is treated as one row. The keys become headers and the values become the single data row.
