02 / what you get
What happens to your data
Kept
- Dates become readable text, for example 2026-01-15
- Formulas are exported as the result they last calculated
- Pretty-printed JSON that any programming language can read
- With several sheets, every sheet is exported, keyed by its name
- The first row of each sheet is used as the header
Good to know
- Colors, fonts, merged cells, charts and images are not part of the data and are dropped.
- Password-protected workbooks cannot be opened.
- Anything around the records in the source file (wrapper elements, comments, metadata) is not carried over.
- With a single sheet the result is a plain array with no sheet name.

XLS vs JSON
XLS
An XLS file is the older Excel workbook format (Excel 97-2003). It still turns up in old exports and archives. Converting it gives you the first sheet as plain data (JSON keeps every sheet), or a modern XLSX.
Used in: Legacy Excel files · Old exports · Archives
JSON
A JSON (JavaScript Object Notation) file stores structured, nested data as readable text — objects, arrays, and key-value pairs. It's the standard format for web APIs and app configuration, so you'll often get one from a developer, an API response, or an app's settings export.
