CSV and JSON — Two Formats, One Tool
CSV (Comma-Separated Values) and JSON (JavaScript Object Notation) are two of the most common data formats on the planet. Spreadsheets export CSV. APIs return JSON. This tool bridges the gap between them — paste one format, get the other instantly.
How CSV to JSON Works
When converting CSV to JSON, the first row is treated as column headers by default (you can disable this). Each subsequent row becomes a JSON object with header names as keys. The result is a JSON array of objects — ready to drop into any API, database import, or script.
Handling Tricky CSV Data
Real-world CSV data isn't always clean. Fields may contain commas or quotes within values. This converter handles double-quoted fields and escaped quotes (double double-quotes) correctly, and supports multi-character delimiters for maximum flexibility.
Custom Delimiters
Not all "CSV" files use commas. TSV (tab-separated), pipe-delimited, and semicolon-separated files are equally common. Pick your delimiter from the dropdown or enter a custom one — the converter adapts instantly.
