02 / what you get
What happens to your data
Kept
- A list of objects becomes the records; if the list sits inside an object (for example {"items": [...]}), the first list found is used
- Keys keep their original order, and keys that appear only in later objects are not lost
- A clean Excel workbook with one sheet, where plain numbers are real numeric cells you can sum and sort
- Booleans become TRUE/FALSE cells and null becomes a blank cell
Good to know
- The file must be strict JSON: comments, trailing commas and single quotes make it invalid and the conversion will fail with the position of the error.
- The result is plain values on one sheet named Sheet1. There are no formulas, styles, column widths or charts.
- Nested objects and lists cannot sit in a table cell, so they are written into the cell as JSON text, for example {"city":"Lviv"}.

JSON vs XLSX
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.
Used in: Web APIs · App configs · Settings exports
XLSX
An XLSX file is a modern Excel workbook: sheets of cells with numbers, text, formulas and formatting. It is the default for spreadsheets today. Converting it gives you the first sheet as plain data (JSON keeps every sheet), so other tools can read it.
Used in: Excel · Business reports · Financial data
