Explore JSON as a collapsible, searchable tree -- expand any branch, search across the whole document, and copy any value or its exact path. Fast, free, and built for simple browser-based workflows.
Viewing happens entirely in this browser tab. The JSON you paste, drop or open here — an API response, a config file, an export with customer data — is never sent anywhere.
Paste some JSON above, drop a .json file, or try the example.

JSON Viewer is a free online tool that shows JSON as an interactive tree you can expand, collapse and search. Paste JSON, open a .json file, or drop one onto the page, then click any row to see its exact path and copy either the path or the value it holds.
It is built for JSON that is too big or too deeply nested to read as text: an API response with hundreds of records, a log export, or a config file several levels deep. Instead of scrolling through thousands of lines, you open only the branches you need. Search covers the whole document, including branches you have not opened yet, and jumps to each match in turn. Arrays longer than 100 items are grouped into blocks of 100, so even a 200,000-item array opens at once. Copy Path gives you the exact expression for reaching a value in code, as JavaScript (data.users[0].email) or JSONPath ($.users[0].email), so you never hand-type a path and get a bracket or quote wrong.
Viewing happens entirely in this browser tab, so the JSON you open here -- a production API response, a webhook payload, a database export with customer records -- is never sent anywhere. The tree shows your data exactly as written: a 20-digit id is never rounded, keys stay in their original order, and a key that appears twice is shown twice with a dup badge instead of one copy quietly disappearing. Nothing is rewritten or reformatted; when you want indented text to copy or download, use JSON Formatter.
Paste JSON into the box, click Open file to choose a .json file, or drag one onto the box. Click "Try an example" to see a sample with a big id and a duplicate key.
Press View JSON, or Ctrl+Enter from anywhere on the page. The first two levels open automatically. If the JSON is invalid, you get the exact line, column and a Go to error link instead.
Click a row to open or close it, or use Expand All and Collapse All. Type in "Search keys and values" to find text anywhere in the document, then use the up and down arrow buttons to step between matches.
Click a row to select it and its path appears under Selected path. Pick JavaScript or JSONPath in Path style, then click Copy Path or Copy Value.
Yes! All our tools are 100% free to use with no hidden costs, no registration required, and no credit card needed.
Absolutely. All tools run entirely in your browser (client-side). Your data never leaves your device and is not sent to our servers.
Yes, once the page is loaded, the tool will continue to work even if you lose internet connection since it runs in your browser.
There is no strict character limit, but very large amounts of text (100,000+ characters) may slow down your browser.
Yes! All our tools are free for both personal and commercial use.
No. JSON Formatter rewrites JSON as indented text you can copy or download. This page does not produce text at all: it shows the document as a tree you open, search and copy pieces from. Use JSON Formatter when you want readable text, and this page when you need to find something inside a large or deeply nested document.
Yes. Search runs over the whole document, not just the rows on screen, so it finds keys and values inside branches you have not opened. It opens the branches around each match, highlights it, and the up and down buttons step between matches. Search ignores upper and lower case, and lists up to the first 1,000 matches.
JavaScript gives an expression you can paste into code after a variable named data, like data.users[0]["first-name"]. JSONPath gives the query syntax used by JSONPath libraries and tools, like $.users[0]['first-name']. Keys that are not plain names, such as ones with a dot, a space or a dash, are put in brackets automatically. Your choice is remembered in this browser for next time.
Arrays with more than 100 items are shown in groups of 100, so a huge array opens at once instead of building thousands of rows. The groups are for display only: a value's path still uses its real index, like data[250], never the group. Selecting a group and clicking Copy Value gives a valid JSON array of just those items.
No. Numbers are shown and copied exactly as typed, including integers too large for JavaScript, which tools built on JSON.parse silently round above about 9 quadrillion. Keys stay in the order they appear in your file, even keys that look like numbers, which JavaScript objects would normally move to the front.
That key appears more than once in the same object. JSON technically allows this, but most parsers keep only the last copy and silently drop the rest. This viewer shows every copy in its original position with a dup badge, and the summary line above the tree says how many duplicates it found.
Yes. Branches are only built when you open them, so even a large document shows its first levels quickly. Above about 10MB of text you will see a brief "this may take a few seconds" notice first. The Open file button accepts files up to about 95MB, and Expand All on a tree with more than 5,000 nodes asks you to click it again to confirm, since opening every row at once can slow the tab down.
No. This page reads standard JSON, so // or /* */ comments and trailing commas are reported as errors with the exact line and column. To view a file like tsconfig.json, run it through JSON Formatter with its JSONC option turned on first, then paste the result here.
No. The tree is read-only, so nothing you click can change your data by accident. To change a value, edit the text in the input box and click View JSON again. The tree is rebuilt and the old search and selection are cleared.
Yes. Click a row first, then use the up and down arrow keys to move between visible rows. The right arrow opens a branch or steps into it, the left arrow closes it or jumps to its parent, and Enter selects the row so its path appears below the tree.
