CSV (Comma-Separated Values) and JSON (JavaScript Object Notation) are two of the most common data interchange formats. CSV excels at tabular data (spreadsheets, databases), while JSON is the standard for web APIs and configuration. Converting between them is a frequent need in data processing workflows.
How to Use
Paste your CSV data:
- Headers: First row is used as JSON keys
- Delimiter: Auto-detected or manually set
- Output: Array of objects or nested format
CSV Format Rules
- Values separated by commas (or custom delimiter)
- Fields containing commas must be quoted: "New York, NY"
- Double quotes inside quoted fields: "He said ""hello"""
- Newlines in fields must be quoted
Data Tips
Clean your CSV before converting: remove trailing commas, ensure consistent column counts, and check for encoding issues (UTF-8 recommended).
