Make nested JSON easier to inspect and map. Flatten objects and arrays into an RFC 6901 pointer-to-value map for data inspection and field mapping. Slash and tilde keys are escaped; empty objects and arrays are preserved. This returns a map, not CSV or a flattened table.

Keep the JSON records that match your next workflow step. Filter by exact equality on a named top-level field, including objects, arrays or null. Missing fields do not match; booleans and numbers stay distinct. Original row order is preserved. Up to 5,000 rows.

Create a focused CSV export with only the columns you need. Select and reorder 1–32 named columns from supplied CSV text. Preserves row order and decoded cell text, then writes correctly quoted CSV. Missing columns are rejected. Useful for cleaner spreadsheet and API handoffs.

Nooscape pre-flight check on an AI agent in an on-chain registry (ERC-8004, Solana), a wallet that registers agents, or an endpoint host: dated flags for first seen, ownership changes, revoked ratings and fleet, with sources. No score, no verdict.

Preview a JSON configuration update without changing an external system. Apply RFC 7396 merge-patch rules to a supplied target: merge object members recursively, delete members set to null, and replace the target for nonobject patches. Returns the patched JSON value only.

A final newline is required; empty-line skipping is optional. Rejects malformed JSON and duplicate keys. Bounded text input, not file reading or streaming.
