JSON Query & Patch
Extract paths, apply RFC 6902 patches, and merge JSON documents.
Querying and patching JSON documents
JSONPath-style extraction pulls nested fields from large API responses without writing jq one-liners. RFC 6902 patch operations apply add, remove, replace, and move changes deterministically, which suits config management and test fixture updates.
Patch operations fail atomically when pointers reference missing paths. Order matters: removing a parent before children yields errors. Merge strategies for duplicate keys should be explicit when combining environment-specific overlays.
Extracted paths help build Grafana variables or webhook filters. Document pointer notation beside runbooks so on-call engineers reproduce the same field isolation during incidents.
Patch and extract locally on responses containing bearer tokens or personal data. Browser execution avoids uploading full documents to remote JSON playgrounds.
