Blobster use case

# Format JSON without publishing it.

Open JSON locally, inspect or edit it, search it and copy the parts you need without uploading the payload.

[Install from Chrome Web Store](https://chromewebstore.google.com/detail/blobster/epddolhfilamhbnmgglenceabjbbeeho) [Blobster overview](https://www.mochavi.com/blobster)

**How can I format JSON privately?**

No account, backend, cloud sync, analytics, telemetry, document upload or public paste URL.

-   No document upload
-   No account
-   No telemetry

## Where Blobster fits.

Open a file, paste a payload, select page text, use a direct URL or open a raw page.

Use tree, raw and table views when they fit the data.

Copy values, subtrees, JSONPath, jq paths, JavaScript paths or redacted output.

## Typical workflow.

Use Blobster as a fast local inspection step before copying, sharing or acting on data.

1.  01 **Open Blobster**
2.  02 **Paste JSON or choose a file**
3.  03 **Inspect, edit, search and copy the needed parts**

## Use the local viewer, not a paste site.

Blobster is built for quick inspection of structured developer data that may contain tokens, customer payloads, headers, internal URLs or support evidence.
