CSV to JSON Converter
Convert CSV data to a JSON array of objects. Paste your CSV and get structured JSON output instantly.
CSV to JSON Conversion Tips
Get clean, well-structured JSON from your spreadsheet data.
Use a Clean Header Row
The first row of your CSV becomes JSON object keys. Use short, descriptive, lowercase names without spaces (e.g., 'first_name' instead of 'First Name') for developer-friendly output.
Quote Values That Contain Commas
If a CSV value contains commas, line breaks, or quotes, wrap it in double quotes as per the CSV standard. This ensures correct parsing.
Verify Type Inference
The converter automatically converts numbers and booleans. If you need a value to stay as a string (like a ZIP code starting with zero), check the output and adjust as needed.

What is CSV to JSON Conversion?
CSV to JSON conversion takes tabular comma-separated data and transforms it into a JSON array of objects. The first row is treated as column headers, and each subsequent row becomes an object.
Input CSV
name,age,city Alice,30,NYC Bob,25,London
Output JSON
[
{ "name": "Alice", "age": 30, "city": "NYC" },
{ "name": "Bob", "age": 25, "city": "London" }
]CSV to JSON FAQ
Does it handle quoted values?
Yes, standard CSV quoting with double quotes is fully supported, including escaped quotes within values.
What delimiter is used?
Comma is the default delimiter. Values containing commas should be enclosed in double quotes as per the CSV standard.
Are types preserved?
Yes, numeric values become JSON numbers and true/false values become JSON booleans. Everything else becomes a string.
What if my CSV uses semicolons or tabs as delimiters?
The converter currently expects commas. For semicolon-separated files, do a find-and-replace to change semicolons to commas before pasting. For tab-separated (TSV) files, replace tabs with commas first.
What happens with empty values in CSV?
Empty CSV cells become empty strings in the JSON output. If the entire value is missing (consecutive delimiters), it will also be an empty string in JSON.
How does it handle newlines inside quoted values?
Standard CSV quoting is fully supported. Values wrapped in double quotes can contain newlines, commas, and escaped quotes (doubled double-quotes) — all parsed correctly.
Can I convert JSON back to CSV?
