SFMC Inspector

SFMC Inspector is a powerful browser extension for Salesforce Marketing Cloud developers and administrators. Works automatically when you're logged into SFMC — no configuration, no OAuth setup, no credentials to enter. FEATURES ▸ Data Extension Explorer Browse all Data Extensions with instant search. Click any DE to see which Automations write to it and which Journeys use it as entry source. ▸ Automation → DE Mapping For any Data Extension, instantly discover which Query Activities target it — including automation name, status, and SQL preview. Click any result to jump directly to the full Automation detail without leaving the Data Extension view. ▸ Journey → DE Mapping See which Journey Builder journeys reference a Data Extension as their entry source, via Event Definitions. ▸ SQL Linter Paste any Query Activity SQL and get instant quality analysis: detects SELECT *, missing NOLOCK on data views, NULL comparison errors, missing WHERE clauses on high-volume tables, GETDATE() without timezone context, and more. ▸ AMPScript Linter Analyse AMPScript blocks from emails, CloudPages and templates: detects missing VAR declarations, IF without ENDIF, LookupRows without null checks, missing EncodeValue(), and more. ▸ Inline SQL Analysis Open any Automation to see its Query Activities with full SQL and automatic quality score — without leaving the extension. ▸ Global Search Search across Data Extensions, Automations and Journeys simultaneously with ⌘K. HOW IT WORKS SFMC Inspector uses your existing browser session — the same session you use to navigate SFMC. No data is ever sent to third parties. Everything stays between your browser and your SFMC account. Built for SFMC architects, developers and administrators.
