Free Mapping Utility

Schema Mapper

Auto-suggest field mappings between two platforms or two schema CSVs. Curated tables for known pairs (Zendesk to Freshdesk, Salesforce to HubSpot); fuzzy name + type matching for the rest. Export a mapping table your engineering team can actually use — all in your browser.

Mapping is one part of sizing a migration. The agent runs this same mapping and adds a complexity score, a timeline from the target’s published API limits, and a flagged risk list.

Ask the Migration Agent
100% client-side. Your schemas never leave this browser. No upload, no telemetry. Safe to map real production fields.
How to read these results: curated = authored mapping, trusted. high = strong fuzzy match, likely correct. review = best guess — verify before using. skip = no confident match (best guess, if any, is in the note column). The tool never auto-assigns a low-confidence match as a real mapping.
