Map messy CSV headers onto a clean target schema. Paste a CSV whose first row holds inconsistent column names (Customer ID, user_id, customerId, CUST_ID…) plus your target schema (one column per line) and an optional "alias=target" dictionary. Each source header is resolved through four layered passes — exact, dictionary, normalized (strips case/accents/separators/camelCase), then fuzzy edit-distance — and shown in a mapping table with method and confidence, plus target coverage and an optional normalized CSV export.

Plan and visualise an API latency budget. Enter a P99 target (e.g. ≤ 300ms) and per-stage allocations (DNS, TCP, TLS, TTFB, Processing, Network) to see a live waterfall, budget utilisation, and over-budget warnings. Optionally paste an OpenTelemetry or Datadog trace to reverse-engineer a measured allocation.
