JSON to CSV Converter
Turn structured JSON objects into flat CSV spreadsheets instantly. Download standard CSV files compatible with Excel, Google Sheets, and more.
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard.
JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.
What is CSV?
CSV (Comma Separated Values) is a plain text format used to store tabular data (numbers and text) where each line of the file is a data record. Each record consists of one or more fields, separated by commas. It is one of the most common formats for data exchange.
Because it's just text, it's highly compatible and can be opened in almost any spreadsheet program like Microsoft Excel, Google Sheets, or simple text editors, making it a universal standard for tabular data.
Why convert JSON to CSV?
JSON (JavaScript Object Notation) is built for nested, hierarchical data, while CSV (Comma Separated Values) is a flat, row-based format preferred by data analysts and business users.
Converting JSON to CSV bridges the gap between developers and non-technical stakeholders. It allows you to export database records or API responses into a format that can be easily opened, filtered, and analyzed in spreadsheet software like Microsoft Excel.
Flattening Nested Data
Our tool employs smart flattening techniques. If your JSON contains nested objects, they are intelligently collapsed into dot-notation column headers (e.g., `user.address.city`), ensuring no data is lost during the transition to a flat table format.
Excel Compatibility
We automatically prepend a Byte Order Mark (BOM) to the output file. This small addition ensures that when you open the CSV in Excel, special characters and Unicode symbols (like emojis or foreign languages) are displayed correctly.

Frequently Asked Questions
Clear answers to common questions
Yes, this is the most common use case. Each object in the array becomes a row in the CSV.
The tool collects all unique keys from all objects to create a comprehensive header row. Missing keys in specific objects will result in empty cells.
Currently, we default to comma (,) which is the standard request for CSV files.
The tool works efficiently with files up to ~50MB directly in the browser.
Nested arrays are typically stringified into a single cell, as CSV cannot natively represent hierarchical lists.
Yes! The generated CSV is fully compatible. Just import it into Google Sheets or Excel.
