How to Convert a JSON to CSV - Easy Steps
Working with JSON data is common for developers and analysts, but turning it into a readable CSV file can be tricky without the right tools. JSON stores information in nested objects and arrays, while CSV files are flat tables. Knowing the proper way to convert JSON to CSV saves time, avoids errors, and makes your data ready for Excel or other spreadsheet applications.
In this guide, we’ll cover multiple ways to convert JSON to CSV, including Excel’s built-in tools, extensions for programming editors, and our fast, privacy-focused online tool. You’ll learn step-by-step methods to ensure clean, structured CSV output every time.
Why Converting JSON to CSV Can Be Tricky
JSON data often contains nested objects or arrays, which do not translate directly into the flat rows and columns of a CSV file. Without proper handling, this can lead to incomplete data, missing fields, or misaligned rows. Understanding these challenges helps you choose the best conversion method.
- Nested arrays may require flattening to appear properly in CSV.
- Large JSON files can cause performance issues in spreadsheet software.
- Different tools or programming editors handle JSON differently.
Method 1: Using Excel’s Built-In Tools (Power Query)
Excel includes Power Query (Get & Transform Data), which allows direct JSON import. This method works well for structured JSON and is ideal if you prefer not to use additional software or extensions.
Step-by-Step Guide:
- Open Excel and navigate to Data > Get Data > From File > From JSON.
- Select your JSON file and click Import.
- Excel shows a preview of your data. Use Transform Data to flatten nested structures as needed.
- Click Load to create the CSV or table in your spreadsheet.
Pro Tips:
- Large JSON files may take longer to load — consider splitting them for efficiency.
- Ensure nested objects are flattened to fit CSV’s tabular format.
- Menu names may vary by Excel version; check your version for exact steps.

FAQs: How to Convert JSON to CSV
What is the easiest way to convert JSON to CSV?
The easiest way is to use a browser-based JSON to CSV converter. Simply upload your JSON file, and the tool will automatically flatten nested objects and arrays, producing a ready-to-use CSV file for Excel or other spreadsheet software.
Can Excel convert JSON files to CSV directly?
Excel cannot directly save JSON files as CSV. You can import JSON using Power Query (Get & Transform Data), transform nested data into a tabular format, and then export it as CSV.
How to convert JSON to CSV using VS Code?
Install a JSON extension in VS Code, such as “Excel JSON Converter” or “JSON Tools.” Open your JSON file, use the extension to flatten the data, and export it as CSV for use in Excel or Google Sheets.
Why do nested JSON objects appear incorrectly in CSV?
Nested objects or arrays can break the CSV format because CSV only supports flat tabular data. Use a converter or script that automatically creates separate rows or columns for nested structures.
How can I preview JSON data before converting to CSV?
Use online preview tools or JSON viewers in VS Code to inspect your JSON structure. This helps ensure consistent keys and proper formatting before exporting to CSV.
Is it possible to automate JSON to CSV conversion?
Yes, automation can be done using scripting languages like Python with Pandas, Node.js scripts, or Excel macros. For one-time conversions, browser-based tools are faster and simpler.
Can I convert large JSON files to CSV without crashing Excel?
Large files can be challenging. Use a dedicated JSON to CSV converter that processes data client-side in your browser or a script that handles chunked processing. This prevents Excel from slowing down or crashing.
Which file formats are supported after conversion?
Most converters export to CSV or XLSX. You can then open the file in Excel, Google Sheets, or other spreadsheet programs.
How to handle missing keys when converting JSON to CSV?
Missing keys in JSON objects can create blank cells in CSV. Use a converter that automatically fills missing columns or ensure consistency in your JSON structure before conversion.
Can I use our JSON to Excel converter to get CSV?
Yes, you can use our JSON to Excel converter and then save the resulting Excel file as CSV. It ensures structured, clean, and accurate output for nested JSON.
