Why JSON iGraph
Exact error locations
Invalid JSON is reported by line and column, so you go straight to the problem.
Private by design
Your data never touches our servers; parsing happens entirely client-side.
Free, no account
No signup, no paywall and no rate limits.
Strict by design
Comments and trailing commas are flagged rather than guessed at, so what you copy out is valid JSON.
What is a JSON viewer and why use one?
A JSON viewer helps you read and understand JSON data by converting raw, unformatted text into a structured, visual format. Instead of scanning through brackets and commas, you can see your data as a graph or tree, making it far easier to spot errors, understand nested relationships, and debug API responses.
JSON iGraph is built around that idea. Paste JSON into the graph to see its structure as connected nodes, use the formatter to beautify it, sort its keys or browse it as a tree, find syntax errors by line and column with the validator, and compare two versions with the diff tool.
Common uses for a JSON graph visualizer
- ✓Debugging API responses during development
- ✓Understanding deeply nested configuration files
- ✓Teaching or learning how JSON data is structured
- ✓Comparing and cleaning up data before database import
Frequently asked questions
Is JSON iGraph free?
Yes. There is no account, no signup and no paywall.
Is my JSON uploaded anywhere?
No. Your JSON is parsed in your browser and there is no server in the path, so there is nothing to upload and nothing to store. You can confirm it in your browser’s network tab.
What can I do with JSON iGraph today?
Four tools, all free and all in your browser. The JSON graph draws any document as an interactive node graph you can search, fold and export as SVG or PNG. The JSON formatter beautifies, minifies and sorts keys, with a collapsible tree view. The JSON validator pins syntax errors to the exact line and column and can repair trailing commas, single quotes and unquoted keys. JSON diff compares two documents side by side.
What is the difference between a graph view and a tree view?
A graph view draws your data as connected nodes, which makes relationships in nested structures easy to follow. A tree view is a collapsible, indented list that is often faster for scanning flat or lightly nested data. JSON iGraph has both: the JSON graph tool, and a tree view inside the JSON formatter.
Does it support JSON5, JSONC or YAML?
Not as input formats yet. Every tool parses strict JSON, so comments and trailing commas are reported as errors rather than guessed at. The JSON validator can repair the most common of them — trailing commas, single quotes and unquoted keys — into strict JSON. JSON5, JSONC and YAML support are planned.
