JSON to CSV Converter

A JSON to CSV converter is an online tool that transforms JSON (JavaScript Object Notation) data into CSV (Comma-Separated Values) format instantly. Whether you're a data analyst exporting API data to Excel, a business analyst preparing reports in spreadsheets, or a developer creating data exports for non-technical users, our converter produces spreadsheet-compatible CSV from JSON arrays and objects.

This tool supports customizable delimiters (comma, semicolon, tab), nested object flattening, automatic header row generation, and CSV file download. Simply paste your JSON array data, configure delimiter options, and get properly formatted CSV ready for Excel, Google Sheets, or any spreadsheet application. The conversion is performed client-side, ensuring your data remains private and secure.

CSV is the universal format for spreadsheet applications and data analysis tools, but modern APIs and web applications output data in JSON format. Converting JSON to CSV is essential for data analysis in Excel, importing into databases, sharing data with business users who need spreadsheet format, and creating data exports that non-technical stakeholders can easily open and analyze.

Data analysts use JSON to CSV converters to export API responses for analysis in Excel or Google Sheets, prepare datasets for data visualization tools, and generate reports that business stakeholders can review. Backend developers benefit from creating data export features, converting database query results to CSV format, and preparing bulk data imports for spreadsheet-based workflows.

The tool saves time by automating the conversion process, flattens nested JSON structures into spreadsheet-compatible rows and columns, and handles proper CSV escaping for special characters. It's particularly valuable when working with API responses that return arrays of objects, exporting large datasets for analysis, or providing data in a format accessible to non-developers.

Data Analysis: Export JSON API responses to CSV for analysis in Excel, Google Sheets, or data visualization tools.

Report Generation: Convert application data from JSON to CSV format for business reports and stakeholder review.

Database Import: Prepare JSON data as CSV for bulk imports into databases, CRMs, or other data systems.

Data Export Features: Provide users with CSV download functionality for application data and reports.

Data Migration: Transform JSON exports from one system to CSV for import into spreadsheet-based systems.

Using our JSON to CSV converter is simple: paste your JSON array data into the input field, optionally select your preferred delimiter (comma, semicolon, or tab), and the converted CSV appears instantly in the output area. The converter automatically generates header rows from object keys and flattens nested structures. Download the CSV file with a single click.

The converter transforms JSON arrays of objects into tabular CSV format, meaning each object becomes a row and object keys become column headers. Nested objects are flattened using dot notation (e.g., user.name becomes a single column). This ensures your CSV output is properly formatted and opens correctly in any spreadsheet application. All conversion happens locally in your browser, keeping your data completely private.
