How it works

Copy CSV from Excel, Google Sheets, or any file.

Auto-detect delimiter or pick one manually.

Copy JSON or download as .json file.

Does it handle quoted fields with commas?

Yes. Fields wrapped in double quotes like "New York, NY" are treated as single values. Escaped quotes inside ("") are also handled.

What does type inference do?

Automatically converts "123" to number 123, "true"/"false" to booleans, and empty cells to null. Turn off if you want everything as strings.

Which delimiters are supported?

Comma, semicolon, tab, and pipe. Auto-detect works for most cases by counting occurrences in the first line.

Is my CSV uploaded?

No. All parsing runs in your browser. Your data never leaves your device.
