ABOUT THIS TOOL

What does CSV to JSON do?

CSV to JSON turns rows from a spreadsheet-style file into a structured JSON array that can be used in APIs, JavaScript, databases, tests, and data pipelines.

Reads your CSV

Choose comma, semicolon, tab, or pipe delimiters. Quoted fields, escaped quotes, and line breaks inside quoted values are preserved.

Builds JSON objects

Use the first row as property names, or generate column names automatically. Numbers, booleans, and null values can be detected.

Stays in your browser

Processing runs locally in your browser. Your input is not uploaded to EveryDevTool while you use this tool.
