CSV to JSON Converter
Convert CSV data into a JSON array of objects.
From spreadsheet rows to structured data
CSV is easy for spreadsheets but awkward for code, which usually wants structured objects. This converts CSV into a JSON array of objects, taking the header row as the keys and turning each data row into an object, so a spreadsheet export becomes data your code can work with directly.
Paste your CSV and it is converted to JSON.
The parsing details that matter
Reliable CSV parsing handles the things that break naive splitting on commas: fields wrapped in quotes because they contain a comma, quotes escaped inside a quoted field, and line breaks within a quoted value. Getting these right is the difference between clean objects and a mangled mess. A subtlety worth noting is that CSV values are all text, so numbers and booleans arrive as strings unless converted — fine for many uses, but something to handle if your code expects real numbers. It pairs with the reverse JSON-to-CSV converter.
Questions & answers
How does it handle commas inside a field?
Correctly — quoted fields containing commas, escaped quotes and line breaks within values are all parsed properly, unlike naive splitting.
Do numbers come through as numbers?
CSV values are text, so numbers arrive as strings unless converted — worth handling if your code expects real numbers.
Is my data uploaded?
No. The conversion happens in your browser.
