CSV to JSON

Convert a CSV file or pasted text into clean JSON — handles quoted commas, and can guess numbers and true/false. Runs entirely in your browser — nothing is uploaded.

Output

Handles the awkward parts of CSV correctly: commas and line breaks inside quoted fields, and doubled quotes ("") as an escaped quote. With "Guess numbers & true/false" on, a value is only converted when the entire cell is a clean number or exactly true/false — so a leading-zero code like 007, or something like 1.2.3, is left as text rather than mangled. If the first row is column names, each row becomes an object; if not, each row becomes an array. Duplicate column names are kept apart (the second "id" becomes "id_1") so nothing is silently overwritten. Everything runs in your browser — nothing is uploaded.

How it works

  1. Upload a CSV file or paste CSV text directly.
  2. The tool parses it, handling quoted commas correctly.
  3. Copy or download the resulting clean JSON.

Frequently asked questions

Does it handle commas inside quoted fields?

Yes, quoted commas are parsed correctly rather than splitting the field.

Will numbers and booleans convert automatically?

Yes, the tool can guess numbers and true/false values from plain text.

Can I paste CSV text instead of uploading a file?

Yes, pasting text works the same as uploading a file.

Your files are never uploaded. Gotool.xyz runs entirely as JavaScript in your browser. Your files are processed in memory and never touch a server — nothing to breach, nothing to clean up. Close the tab and it's like it never happened. The only thing we count is which tool ran (just the name, e.g. "merge") so we know what people find useful — never your file, its name, its size, or anything in it.
