How do I convert a JSON file to XLS?

Upload your JSON file, select XLS as the output format, and click Convert. Our tool parses JSON arrays into rows and objects into columns, mapping each key to a column header. Nested structures are flattened automatically, so you can download an organized XLS spreadsheet in seconds.

How does the conversion handle nested JSON objects and arrays?

Nested objects are flattened into dot-notation column headers (e.g., user.name), while arrays are either expanded across multiple rows or serialized as JSON strings in a single cell, depending on the data structure. Primitive data types like numbers, booleans, and dates are preserved as native XLS cell types, ensuring formula compatibility.
