02 / what you get
What happens to your data
Kept
- The first row is used as the header and empty lines are skipped
- The separator is detected for you (comma, semicolon, tab or pipe), so exports from regional Excel versions work
- Quoted cells that contain separators, quotes or line breaks are read correctly
- Pretty-printed JSON that any programming language can read
- Plain numbers become JSON numbers; values like 007 or long IDs stay text so nothing is altered
Good to know
- Values arrive as text and become numbers only where that is unambiguous and the target can hold numbers.
- Anything around the records in the source file (wrapper elements, comments, metadata) is not carried over.

CSV vs JSON
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
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.
