02 / what you get
What happens to your data
Kept
- The first row is used as the header and empty lines are skipped
- Quoted cells that contain tabs, 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
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.
03 / formats
TSV vs JSON
TSV
A TSV (Tab-Separated Values) file is just like CSV, but it uses tabs instead of commas to separate columns. It's handy when the data itself contains commas — like addresses or descriptions — since tabs won't get confused with the content.
Used in: Spreadsheet exports · Data containing commas · Bioinformatics data
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
