CSV to JSON Converter
Convert CSV data to JSON online with header mapping and smart type detection, no upload needed
CSV to JSON Tips
- With the header option on, the first row becomes object keys and every other row becomes an object.
- Type detection turns 42 into a number, true/false into booleans, and empty cells into null - turn it off to keep everything as strings.
- Quoted fields may contain commas, quotes (doubled), and even line breaks - all handled per RFC 4180.
- Auto-detect counts commas, semicolons, and tabs in the first line and picks the most common one.
전문적인 CSV to JSON Converter 처리 기능
CSV to JSON Converter 데이터를 효율적이고 전문적으로 다루는 데 필요한 모든 것
Real CSV Parsing
An RFC 4180 state machine, not split-by-comma: quotes, escaped quotes, and embedded newlines all parse correctly.
Header Mapping
The first row becomes object keys, producing clean arrays of objects ready for APIs.
Type Detection
Numbers, booleans, and null are coerced automatically - or kept as strings with one click.
Delimiter Flexibility
Auto-detection plus manual comma, semicolon, and tab options for any locale.
Instant Conversion
Thousands of rows parse in milliseconds with zero network activity.
Private by Design
Data stays in your browser tab. Close it and everything is gone.

전문가가 구축
CSV looks simple until values contain commas, quotes, or line breaks - then naive split-by-comma parsers silently corrupt your data. This converter implements a real RFC 4180 state machine: it tracks quote state character by character, maps the header row to object keys, and optionally coerces numbers, booleans, and null so the output is ready for APIs, MongoDB imports, and JavaScript.
주요 기술 기능:
- • Full RFC 4180 parser: quoted fields, escaped quotes, embedded newlines
- • Header row mapped to object keys automatically
- • Optional type detection for numbers, booleans, and null
- • Delimiter auto-detection or manual selection
- • Pure client-side conversion - your data never leaves the browser
신뢰 및 보안
Built for developers who feed spreadsheets into scripts and APIs. The parser runs entirely in your browser, so customer lists and exports are never uploaded anywhere.

자주 묻는 질문
Csv To Json 서식 지정에 대한 일반적인 질문에 답변합니다
Yes, completely free with no registration. All parsing happens locally in your browser.
Yes, as long as the field is quoted per RFC 4180. The parser correctly handles embedded commas, doubled quotes (""), and multi-line quoted fields - things that break naive split() approaches.
Yes. Turn off the "First row is the header" option and every row - including the first - is emitted as a plain array of strings.
Values that parse as finite numbers become JSON numbers, the exact strings true and false become booleans, and empty cells become null. Any other value stays a string. Disable the option to keep every value as a string.
Yes. Leave the delimiter on auto-detect (it counts candidate delimiters in the first line) or select semicolon or tab manually.
