CSV to JSON

How to use CSV to JSON

1. Paste valid source-format data into CSV to JSON.
2. Confirm the source structure matches the expected input format.
3. Run CSV to JSON to generate the target format.
4. Inspect nested values and escaping before copying the converted result.

Common uses

• A QA engineer can convert a spreadsheet export into deterministic API test fixtures.
• A frontend developer can turn a small product table into objects for a prototype without writing parsing code.

Example input

name,age
Alice,30
Bob,25

Example result

[
  { "id": "101", "name": "Ada Lovelace", "city": "London" },
  { "id": "102", "name": "Grace Hopper", "city": "New York" }
]

Common mistakes

• Rows contain different field counts. Fix: locate stray delimiters or add the missing empty field.
• A value contains a comma but is not quoted. Fix: wrap the complete value in double quotes.
• The wrong row is used as headers. Fix: remove report titles or preamble rows so the first data definition row contains unique column names.

Tips for reliable results

• Check one representative nested record before converting a large input.
• Review arrays, attributes, null values, dates, and leading zeros because formats represent these values differently.
• Validate the generated output with a target-format validator before importing it into another system.
