Overview
This Google Sheets™ add-on makes it easy to audit and monitor your Google Analytics 4 setup—helping you catch tracking issues, broken funnels, misconfigured UTM parameters, and more.

Built for marketers, ecommerce brands, and analysts who rely on clean data to make confident decisions.
Key features of this Google Sheets™ add-on:
Instantly audit your GA4 property across 10+ categories:

■ Detect data quality issues and configuration gaps
■ Monitor event anomalies with daily alerts
■ Validate ecommerce tracking, UTM structure, and Google Ads integrations
■ Customize thresholds, ignore rules, and notification preferences
■ No setup required—just connect your GA4 property and start auditing
■ All features are available for free (see license section for limits on scheduling)

► We do not access or store your data
Your GA4 data stays entirely within your Google account.
 This add-on uses only official Google APIs (via OAuth) to query GA4 data and display results directly in your spreadsheet.
 We do not collect, transmit, or store any of your analytics data—ever.
Even license validation is handled securely via a lightweight API and never accesses your GA4 data.

► Scheduling limitations
The free version includes all features.
 However, scheduling audits for multiple GA4 properties requires a license.
Licensed users can monitor several GA4 properties on a daily schedule. Free users can schedule audits for one property only.
