CSV to JSON Converter
Paste comma-separated CSV data below and convert it into a clean, structured JSON array — the first row is treated as your column headers.
How to Use the CSV to JSON Converter
- Paste your CSV data into the input box, with the first line as the header row.
- Click "Convert to JSON". Each subsequent row becomes one JSON object keyed by the header names.
- Quoted fields (containing commas or quotes) are parsed correctly, not just split on every comma.
- Click "Copy" to copy the JSON, or "Download data.json" to save it as a file.
Why Use This Tool?
Is my CSV data uploaded anywhere?
No. The parsing happens entirely in your browser with JavaScript — nothing is sent to a server or stored. This matters because CSV exports from CRMs, spreadsheets or databases often contain customer names, emails or other sensitive records you shouldn't paste into a random online tool that logs input; this one never does.
Does it handle quoted fields correctly?
Yes. The parser understands double-quoted fields that contain commas, line breaks, or escaped quotes (written as two double quotes in a row), which is the standard CSV quoting convention used by Excel and Google Sheets exports.
What if my CSV uses semicolons instead of commas?
This tool expects comma-delimited CSV, the most common format. If your file uses semicolons (common in some European locales), find-and-replace the delimiter with a comma first, taking care not to touch commas inside quoted text fields.
Who uses a CSV to JSON converter?
Developers importing spreadsheet data into an API or database, data analysts prepping test fixtures, and no-code builders feeding structured data into JavaScript apps all need a fast, accurate way to turn tabular CSV into JSON objects without writing a parser from scratch.
