How to Convert CSV to JSON
CSV (Comma-Separated Values) and JSON (JavaScript Object Notation) are two of the most common data formats. Converting between them is essential for data processing.
CSV vs JSON
- CSV: Tabular data, human-readable, small file size
- JSON: Nested structures, data types preserved, widely used in APIs
When to Use Each
Use CSV for spreadsheets and flat data. Use JSON for APIs and hierarchical data.
