Blobster use case

# Open \`.jsonl\` files line by line.

Blobster treats JSON Lines as records, so logs do not appear as one invalid JSON document.

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

**How do I open a JSONL file?**

JSONL and NDJSON are close workflows in Blobster. Both stay local and keep raw source available.

-   No document upload
-   No account
-   No telemetry

## Where Blobster fits.

Detect \`.jsonl\` filenames and pasted line-delimited JSON.

Show object-like rows as a table where practical.

Copy valid rows or inspect one record at a time.

## Typical workflow.

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

1.  01 **Open a \`.jsonl\` file**
2.  02 **Use table search to find a row**
3.  03 **Select a record to inspect and copy it**

## 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.
