A practical way to inspect API responses, customer payloads and configuration data without turning sensitive debugging material into somebody else’s input.
HAR captures are excellent debugging evidence, but they can also carry headers, cookies, URLs, request bodies and customer context. Review and reduce them locally first.
One malformed line should not hide a useful log or export. Learn how newline-delimited JSON differs from a JSON array and how to isolate bad records.
JSONPath, jq and JavaScript property access look similar, but they solve different jobs. Use the selected value to produce the right syntax without retyping it.
Open the file from disk in Blobster instead of pasting it into a web formatter. Files up to 25 MB become a tree straight away, bigger files open as raw text until you ask for the tree, and large CSV, TSV, NDJSON and JSONL files stream into a table. Nothing leaves your browser.
Open the YAML file in Blobster, check the tree and copy the top-level value. Blobster copies it as indented JSON, and the conversion runs in your browser, so manifests and configs with internal hostnames or credentials never reach a converter site.
Open the payload in Blobster, delete the parts the reader does not need, then use Copy redacted. Blobster replaces the values of secret-looking keys, such as password, token, api_key, authorization and cookie, with [REDACTED]. It matches key names, not values, so read the result before you send it.
Open the openapi.yaml or openapi.json file in Blobster. It recognises OpenAPI 3 documents, lists every operation with its parameters, schemas and responses, and can send a test request to a server you choose. The spec itself is never uploaded. Swagger 2.0 files open as a plain tree.
Open the first file in Blobster, open the Compare pane and choose the second file. Blobster lists every changed, added, removed and retyped value with its path, ignores key order and matches array items by their id where it can. Both files stay in your browser.
Open the document in Blobster, open the Query pane and type a JSONPath expression such as $..email or $.items[*].id. Blobster lists every match with its path as you type and copies the matched values as a JSON array. The document stays in your browser.
