Convert CSV Database Exports to JSON Arrays for APIs and Apps
CSV is how databases, CRMs, and spreadsheets export data — but REST APIs, JavaScript applications, and modern data pipelines expect JSON. CSV-to-JSON converts each CSV row into a JSON object using the header row as property keys, producing a clean JSON array that's ready for JSON.parse(), pandas.read_json(), MongoDB import, or POST to any REST API.
How to Convert CSV to JSON
Click "Convert Now" to open the document converter with CSV → JSON already selected.
Drag and drop your CSV file or click Browse. Works with exports from Excel, Google Sheets, Salesforce, Shopify, and any tool with CSV export.
Conversion runs entirely in your browser — delimiter auto-detected, values typed automatically.
Your JSON array downloads immediately, ready for APIs, databases, or JavaScript processing.
CSV Rows to JSON Objects: Bridging Database Exports and Modern APIs
Every major database, SaaS platform, and spreadsheet application has a "Export to CSV" button. Almost no modern web application or API accepts CSV as input — they expect JSON. This mismatch is one of the most common friction points in data pipelines. Salesforce exports contacts as CSV; your Node.js backend expects JSON. Google Analytics exports data as CSV; your Python analytics script uses pandas with JSON. Shopify order exports are CSV; your fulfillment API accepts JSON payloads. CSV-to-JSON closes this gap by reading the CSV header row as JSON property names and each subsequent row as a JSON object, then wrapping all objects in a JSON array. The result is [{"name":"Alice","email":"alice@example.com"}, ...] — exactly the format that Array.map(), MongoDB's insertMany(), and REST API POST bodies all expect natively.

Frequently Asked Questions
[{"id":"1","name":"Alice"}, {"id":"2","name":"Bob"}]."age":"25" become "age":25 in the output.null in the JSON output, which is the JSON representation of a missing/empty value. This is consistent with how most APIs and databases handle absent fields.mongoimport tool accepts a JSON array file with the --jsonArray flag: mongoimport --jsonArray --file output.json --collection mycollection. The output format is compatible with this command.
