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
  • Saved as UTF-8 with a BOM, so Excel shows Ukrainian, Polish and other non-Latin letters correctly

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.
  • Commas, quotes and line breaks inside a value are wrapped in quotes automatically so the columns stay aligned.
  • 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 CSV

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

CSV

A CSV (Comma-Separated Values) file stores tabular data as plain text — each line is a row, commas separate the columns. It's the most universal way to move spreadsheet data between programs: Excel, Google Sheets, databases, and most apps can all read it.

Used in: Excel & Sheets exports · Database exports · Data sharing
