CSV vs JSON: When to Use Each Format
Understand the differences between CSV and JSON data formats and when to convert between them.
CSV and JSON are the two most common data interchange formats. CSV is flat and spreadsheet-friendly. JSON is hierarchical and API-friendly. Choosing the right format saves time and prevents data loss.
When to use CSV
- Exporting data to Excel or Google Sheets

- Importing into databases or CRM systems
When to use JSON
- API requests and responses
- Nested or hierarchical data structures
