Your input stays in the browser.

JSON Explorer uses its verified local execution path and does not create a hidden input or output history.

Local execution

Runs inside the current browser tab.

No hidden processing

Active tool data never becomes a Toolars document record.

No account required

Use the core workflow without creating a profile. Favorites sync to your account after you sign in.

Immediate reset

Clear the tab and the active working data is gone.

What JSON Explorer actually does

Query JSONPath, extract fields and round-trip JSON Pointer records without losing large-number precision.

Common questions

What does JSON Explorer support?
JSONPath subset: child names, indices/unions, wildcards, recursive names, slices and primitive field filters. No scripts. Flatten uses ordered JSON Pointer records, including empty containers; CSV/TSV/XLSX requires flat object rows and exports cells as strings.
Does JSON Explorer upload my content?
Your content stays in page memory. Processing runs locally; navigation or reload clears it.
What limits apply to JSON Explorer?
256 KiB combined input; 5,000 input rows; depth 40; 10,000 nodes; 2 MiB output. Processing stops after 3 seconds; worker startup allows 15 seconds.
