CSV to JSON vs JSON to CSV
The same data, two directions: one feeds APIs, the other feeds spreadsheets.
CSV and JSON are the two most common data formats for moving tabular information between systems. CSV to JSON converts spreadsheet rows into structured JSON for applications; JSON to CSV does the reverse for Excel or Google Sheets.
CSV to JSON reads a CSV file or pasted text, auto-detects the delimiter, and produces an array of objects with headers as property names. It is the standard way to turn spreadsheet exports into API-ready data.
JSON to CSV flattens JSON objects into rows and columns, handling nested fields with dot-notation headers. It is what you use to export an API response into a spreadsheet for analysis.
