CSV to JSON Converter
This CSV to JSON converter parses spreadsheet-style CSV data into a JSON array, where each row becomes one object and each column header becomes a key. You can configure the delimiter (comma, semicolon, tab, or pipe) and quote character to match your source file, and handle files with or without a header row. Conversion runs entirely in your browser, so nothing is uploaded.
Frequently asked questions
How do I convert CSV to JSON?
Paste your CSV data into the editor and it is converted automatically into a JSON array of objects, one object per row, ready to copy or download.
Does it support delimiters other than commas?
Yes. Commas, semicolons, tabs, and pipes are all supported, so you can convert semicolon-separated or tab-separated (TSV) files the same way.
What happens if my CSV has no header row?
Uncheck the "First row is header" option and the columns are keyed generically as col1, col2, col3, and so on, instead of using values from the first row.
How are quoted fields and embedded commas handled?
You can set the quote character to match your source file, so fields wrapped in quotes — including ones that contain the delimiter itself — are parsed as a single value instead of being split.
Is my CSV data uploaded when I convert it?
No. The conversion happens entirely in your browser, so the CSV content is never uploaded, logged, or sent to a server.
