HubSpotHandling duplicate Contact IDs when syncing Google Sheets torequires detection strategies and clear resolution rules. The key is identifying duplicates before sync and deciding which record should take precedence during updates.
Here’s how to detect duplicate Contact IDs and set up automated handling strategies that maintain data integrity during synchronization.
Prevent sync conflicts with duplicate Contact ID detection using Coefficient
Coefficientprovides several strategies for handling duplicate Contact IDs during Google Sheets to HubSpot synchronization. The pre-export validation approach uses Google Sheets formulas combined with Coefficient’s conditional export features to identify and flag duplicate Contact IDs before syncing.
Use COUNTIF formulas to identify duplicate Contact IDs, conditional formatting to highlight duplicates visually, and Coefficient’s conditional export logic to skip duplicate rows automatically.
How to make it work
Step 1. Set up duplicate detection formulas in Google Sheets.
Create a helper column using COUNTIF(A:A,A2)>1 to identify duplicate Contact IDs, where column A contains your Contact IDs. Add conditional formatting to highlight duplicates in red. Use Google Sheets UNIQUE function or pivot tables to create a summary of duplicate Contact IDs for review.
Step 2. Implement data deduplication strategies.
Choose your handling approach: Last Row Wins (process duplicates sequentially with the last occurrence overwriting previous updates), Conditional Logic using Coefficient’s formula-based conditions to determine priority based on timestamp data, data completeness, or priority indicators, or Error Prevention by filtering out duplicate Contact IDs entirely from export operations.
Step 3. Configure automated duplicate prevention.
Create Google Sheets data validation rules preventing duplicate Contact ID entry in the first place. Set up Coefficient’s scheduled imports to refresh Contact ID lists and identify discrepancies. Configure Coefficient alerts to notify you when duplicate Contact IDs are detected, and establish a staging process to test duplicate handling with small datasets before full synchronization.
