Filtering

The filter panel lets you focus on specific parts of a large JSON document. Open it from the Filter button in the toolbar.

Filter modes

Mode	Description	Example
Key	Match against object key names	`name` matches all keys named “name”
Value	Match against values	`active` matches values containing “active”
Path	Match by JSON path pattern	`$.users[*].email`
JMESPath	Advanced query expressions	`users[?age > 18].name`
JavaScript	JavaScript filter function	`item.price > 100`

Display modes

After entering a filter expression, choose how results are displayed:

Highlight mode

Matching paths are highlighted in the tree with a visual indicator. Non-matching paths remain visible but dimmed. This is non-destructive — your data is unchanged.

Filter mode

Non-matching paths are hidden from the tree view. Only matching nodes and their parent paths are visible. The status bar shows the count: e.g., “Showing 12 of 350 paths”.

Filtering is view-only — it never modifies your data. Clearing the filter restores the full tree.

Filter by key

Matches object keys containing your search text.


Filter:  email
Matches: all nodes where the key name contains "email"
         (e.g., "email", "emailAddress", "primaryEmail")

Filter by value

Matches nodes where the value (as a string) contains your search text.


Filter:  admin
Matches: all values containing "admin"
         (e.g., "admin", "administrator", "admin@example.com")

Filter by path

Uses JSONPath-style patterns to match specific locations in the document.


Filter:  $.users[*].name
Matches: the "name" field of every item in the "users" array

Filter by JMESPath

Uses JMESPath expressions for powerful queries.


Filter:  users[?age > `18`].name
Matches: names of users where age is greater than 18

Filter by JavaScript

Write a JavaScript predicate function. The variable item refers to each array element, and index is its position.


Filter:  item.price > 100 && item.inStock
Matches: array items where price > 100 and inStock is true

JavaScript filter mode is only available when the root JSON is an array. It evaluates the expression for each array item.

When matches are found, use the Previous and Next buttons (or keyboard shortcuts) to cycle through them. The tree auto-expands and scrolls to reveal each match.
