Common situations

Start from what you need to do

Choose the right direction first

API payloads usually arrive as JSON arrays, while marketing exports or spreadsheet data are often easier to share as CSV.

Watch headers and delimiters

CSV conversion quality depends on the header row and delimiter choice. Always check whether you need commas, semicolons or tab-separated output.

Validate structure before sharing

If you convert CSV into JSON, inspect the resulting object array before passing it to another tool or API.
