도구 소개
Turn CSV into a JSON array with one row per object. Optional header detection, configurable delimiter, and type coercion that turns 1/true/null into real JSON values.
도구 개요
The parser is RFC-4180 compliant: it handles quoted fields, escaped quotes ("" → "), mixed \n and \r\n line endings, and trailing blank lines. With header mode on, the first row becomes the JSON object keys; with it off, each row is output as an array. Type coercion converts bare integers, floats, true/false, and null into their JSON-native form — leaving ambiguous strings (like "007" or "01-02") alone.

{ "product": "Gadget", "price": 42, "notes": "ships 2 weeks" }
]TSV input with the header row disabled outputs an array of arrays. Numeric cells are coerced to numbers.

자주 묻는 질문
Is this CSV to JSON converter free?+
Yes. Convert as much as you need — unlimited rows, no sign-up, no upload to any server.
Does it support tab-separated or semicolon-separated files?+
Yes. Change the delimiter option to Tab, Semicolon, or Pipe before converting. Excel exports from European locales typically use semicolons.
What is type coercion?+
When enabled, 1 becomes the number 1, "true" becomes the boolean true, and "null" becomes null. Turn it off to keep every cell as a string — useful when you want to preserve leading zeros like "007".
Can it handle quoted fields with commas inside?+
Yes. The parser follows RFC 4180: "a, b" is a single cell containing "a, b", and "" inside a quoted cell is treated as a literal double quote.
Is the first row always treated as the header?+
Only when the "First row is header" option is on (default). Turn it off and you get an array of arrays instead of an array of objects.
