What is JSON Parser?
Ever stared at a wall of JSON and wished you could just see it as a table? That's exactly what this tool does. JSON Parser takes your JSON (JavaScript Object Notation) data and turns it into interactive HTML tables you can actually work with.
Whether you're debugging an API response, analyzing data exports, or trying to make sense of a config file, this tool saves you time. No more manually parsing through nested objects or writing scripts just to view your data. According to MDN Web Docs, JSON is the most common data format for APIs, and our parser handles all standard JSON structures.
The best part? Everything runs in your browser. Your data never touches our servers unless you explicitly share it. It's fast, free, and private.
What Makes This Tool Different
Real Tables, Not Just Formatting
Most JSON viewers just prettify the code. This one actually converts arrays into rows and objects into columns. Nested data? Gets its own expandable table. It's like having Excel for JSON.
Edit Right in the Table
Found a typo? Double-click and fix it. Changes sync back to the JSON automatically. No copy-paste, no manual editing – just click and type. Works great for quick data fixes.
Search Without Scripts
Type in any column header to filter rows instantly. Need to find all users from a specific city? Just type it in. No need to write filter functions or grep through files.
Go Fullscreen
Click maximize and the table takes over your screen. Perfect when you're dealing with wide datasets or need to show data to someone. All the filtering and editing works there too.
Export to Excel
One click downloads your table as an .xls file. Open it in Excel, Google Sheets, or any spreadsheet app. Handy when you need to do pivot tables or share data with non-developers.
Share Links
Generate a link to your JSON and send it to teammates. They can view it without pasting anything. Set expiration times – 1 hour, 1 day, or 1 week. Useful for debugging sessions.
How It Works
Paste Your JSON
Grab JSON from anywhere – your API response, a config file, database export, or even from Postman. Paste it in the left editor. Not sure what JSON looks like? Click "Sample" to see an example. The editor provides syntax highlighting, so you'll spot errors quickly.
Watch It Transform
As soon as you paste, the table appears on the right. Arrays turn into rows, object properties become columns. Got nested data? It shows up as tables within tables. The parsing follows the RFC 8259 JSON specification, so it handles everything standard JSON supports.
Filter and Fix
Type in the filter boxes at the top of each column to narrow down results. Need to fix a value? Click "Edit" and double-click any cell. The change shows up in the JSON editor immediately. It's like editing a spreadsheet, but your JSON stays valid.
Export or Share
Download as Excel if you need to work with it in Microsoft Excel or Google Sheets. Or generate a share link to send to teammates. Everything runs client-side using JavaScript's native JSON.parse() – fast and private.
When You'd Actually Use This
Debugging API Responses
Your API returns JSON, but you can't tell if the structure is right. Paste it here, see it as a table, and spot missing fields instantly. Works great with Swagger/OpenAPI responses or GraphQL queries. Much faster than writing a script just to view data.
Quick Data Analysis
Got a JSON export from your database or analytics tool? Instead of writing Python scripts or loading it into a database, paste it here. Filter what you need, export to Excel, and you're done. Perfect for one-off analysis tasks without the overhead.
Config File Reviews
Trying to understand a complex JSON:API config or settings file? View it as a table to see the structure clearly. Edit values directly if you need to make changes. Way easier than hunting through nested braces.
Showing Data to Non-Devs
Need to show JSON data to a PM or designer who doesn't read code? Generate a share link and send it over. They see a clean table instead of raw JSON. Saves you from explaining what brackets mean.
Common Questions
Do you store my JSON data?
Nope. Everything runs in your browser using JavaScript. Your JSON never leaves your computer unless you click "Share" to create a link. Even then, you control when it expires. We follow the same privacy principles as tools like JSON Formatter – process locally, keep it private.
What JSON formats work?
Anything that's valid JSON according to the ECMA-404 standard. Arrays, objects, nested structures, mixed types – all of it. If JSON.parse() can handle it, so can we. Complex nesting just creates more nested tables.
Can I edit the data?
Yes. Click "Edit" and double-click any cell. Change the value, hit Enter, and it updates the JSON automatically. You can also remove columns entirely if you don't need them. It's like editing a spreadsheet, but your JSON stays syntactically correct.
How does filtering work?
Type in the boxes at the top of each column. It filters rows that contain your search term in that column. You can filter multiple columns at once – it shows rows that match all your filters. Case-insensitive, so "john" finds "John" too.
What can I export to?
Right now, Excel (.xls format). Opens in Excel, Google Sheets, LibreOffice – basically any spreadsheet app. The table structure stays intact, so nested data becomes nested tables in Excel too. We're looking at adding CSV export soon.
How big can my JSON file be?
No hard limit, but performance depends on your browser. Small files (under 1MB) parse instantly. Files around 5MB might take a second or two. Really huge files (10MB+) can slow things down, but they'll still work. If you're dealing with massive datasets, consider using a tool like jq for command-line processing.
Other JSON Tools You Might Need
This parser is great for viewing data, but sometimes you need other things. Here are our other tools that work well together:
