About the CSV to JSON Converter
Paste your data or load a file and convert in either direction. The CSV parser handles quoted fields, embedded commas and line breaks inside quotes properly, so exported spreadsheets do not fall apart.
Numbers and true/false values can be converted to real JSON types instead of strings, and a table preview lets you check the result before downloading.
Frequently asked questions
My CSV has semicolons, not commas
Change the delimiter — semicolon, tab and pipe are all supported. European Excel exports normally use semicolons.
Can I convert nested JSON?
Nested objects are written into the CSV cell as JSON text, since CSV has no way to express structure. Flatten the data first if you need proper columns.
