If you’ve worked with APIs, you’ve probably received JSON responses that needed to be shared with non-technical users. While developers are comfortable reading JSON, most business users prefer Excel.
I often found myself converting API responses into spreadsheets for testing, reporting, and debugging. Existing online tools either had file-size limits, required sign-ups, or struggled with nested JSON.
That motivated me to build a free JSON to Excel converter.
Why Convert JSON to Excel?
Here are a few common scenarios:
- Export API responses for business teams.
- Analyze data using Excel filters and pivot tables.
- Share information with clients.
- Verify API responses during testing.
- Create reports from JSON datasets.
Challenges I Faced
Building a converter sounds simple until you encounter real-world JSON.
Some of the biggest challenges were:
- Nested objects
- Arrays inside objects
- Missing properties
- Large datasets
- Different data types
- Invalid JSON input
A good converter should gracefully handle all of these cases.
My Approach
The converter performs the following steps:
- Validate the JSON.
- Parse the data.
- Flatten nested objects into column names.
- Convert arrays into readable values.
- Generate an Excel workbook.
- Allow users to download the file instantly.
This approach works well for most API responses.
Features
- No registration required
- Works directly in the browser
- Supports nested JSON
- Handles arrays
- Fast conversion
- Free to use
Lessons Learned
Building this project taught me that usability is just as important as functionality.
Helpful error messages, clean output, and a simple interface make a much bigger difference than adding dozens of advanced options.
