How this service works
一个人的思考、创作与成长记录。关于生活、技术、商业和一切有趣的事。
Output
Returns a JSON object containing a 'rows' array, where each element is a JSON object with keys derived from the CSV header row and values from the corresponding data row. For example, a CSV with headers 'name' and 'age' yields rows like [{"name":"Alice","age":"30"}]. All values are returned as strings.
Example use cases
Spreadsheet data into API payload
“I have this CSV export from our CRM — 'id,email,plan\n1,alice@example.com,pro\n2,bob@example.com,free' — can you convert it to JSON so I can feed it into our billing API?”
Data pipeline format conversion
“Take this CSV chunk from our analytics export and turn it into a JSON array of objects: 'date,clicks,impressions\n2024-01-01,500,10000\n2024-01-02,430,9500'”
Normalize user-uploaded file
“A user just uploaded a CSV file with columns 'product,price,stock' and three rows of data — convert it to JSON rows so I can insert them into the database.”
Technical details
Endpoint
POSThttps://leoshi-blog.vercel.app/api/tools/csv2jsonWhen to prefer
Choose this endpoint when you need a quick, low-cost conversion of CSV text to JSON without standing up your own parser. Ideal for lightweight data pipeline steps, handling user-uploaded CSVs, or transforming export data before feeding it to another API. At $0.01 per call it is well-suited for occasional on-demand conversions rather than high-volume batch processing.
Side effects
- Malformed or empty CSV input may return an error or empty rows array
- CSV with inconsistent column counts per row may produce misaligned key-value pairs
- Missing header row could result in unnamed or incorrectly keyed fields
- Very large CSV payloads may time out or be rejected
