JSON to CSV Converter – Convert JSON Arrays to CSV
This JSON to CSV converter flattens an array of JSON objects into rows with headers, or treats a single object as one row. Columns follow the first appearance of each key. Values containing commas, quotes, or newlines use RFC-4180 quoting with doubled quote escapes. Choose a tab or semicolon delimiter when needed for a European locale.
JSON to CSV converter turns a JSON array of objects into CSV rows, with headers based on the object keys. You can also convert a single JSON object, which is treated as one row. Use the tool to make JSON data easier to inspect or prepare it for a workflow that accepts CSV.
The conversion flattens the objects into rows and columns. Column order follows the first appearance of each key. Values containing commas, quotes, or newlines are quoted according to RFC 4180, with quote characters doubled inside the value. A tab or semicolon delimiter is available for European locales.
JSON represents structured data, while CSV presents tabular data as rows and columns. Converting JSON to CSV can help when a system or workflow needs a table rather than JSON. The output preserves the data in a CSV-oriented form, but CSV does not represent JSON's structure in the same way.
The conversion runs entirely in your browser: your input is processed on your device and is not sent to a server. The tool works offline once the page has loaded, so you can convert data without an active connection.
This JSON to CSV converter is useful for developers and DevOps engineers who need to review JSON as a table, prepare data for another system, or check a conversion before using the result. It also helps anyone who needs a quick way to convert JSON to CSV online and copy the output.
Step 1: Paste a valid JSON array of objects, or paste a single JSON object. The converter turns the input into CSV rows.
Step 2: Choose a delimiter if needed. Tab and semicolon delimiters are available for European locales.
Step 3: Review the CSV headers and values. Column order follows the first appearance of each key, and values containing commas, quotes, or newlines are quoted with doubled quote escapes.
Step 4: Copy the CSV result and use it in your next tool, document, or workflow.
Use case: Move JSON data into a system that accepts CSV but not JSON. Convert the objects into rows and columns, then copy the result.
Use case: Check whether a CSV value you received matches the original JSON. The converter provides a consistent view of the JSON data as CSV.
Use case: Prepare JSON snippets for documentation, a ticket, or a commit message. Convert them to a tabular format that is easy to review.
Use case: Sanity-check a conversion before pasting the CSV result into code. Review the headers, column order, and quoted values first.
Use case: Prepare object data for a workflow that expects tabular CSV input. Choose a tab or semicolon delimiter when that suits the destination or locale.
Use case: Create a readable CSV version of a small JSON example for a technical discussion. A single object becomes one row, while an array of objects becomes multiple rows.
