Conversor de CSV a JSON

How It Works

1. Paste CSV or upload a file: Enter CSV data directly or upload a .csv file. The tool auto-detects the delimiter (comma, tab, semicolon, or pipe).
2. Configure options: Set whether the first row is a header (used as JSON keys), how to handle empty values, and whether to auto-detect number types.
3. Convert: Each CSV row becomes a JSON object with keys from the header row, or a plain array if there's no header.
4. Copy or download: Copy the JSON array or download as a .json file for use in code or APIs.

Why Convert CSV to JSON?

CSV is the universal data export format for spreadsheets, databases, and analytics tools — but most modern APIs, JavaScript applications, and NoSQL databases work with JSON. Converting CSV exports from Google Sheets, Excel, Airtable, or database tools to JSON is a daily task in data engineering, web development, and API integration work. This converter handles common CSV edge cases: quoted fields containing commas, escaped quotes inside quoted fields, Windows-style line endings (CRLF), and mixed number/string columns with smart type detection.

Features

• Auto delimiter detection — comma, tab, semicolon, or pipe
• Header row support — first row used as JSON key names
• Type coercion — numbers and booleans detected automatically
• Large file support — handles files with thousands of rows
• Pretty-print option — indented or compact JSON output
