Google Ads Offline Conversion Switch from Google Sheet to Hubspot

[UCL]

I have an offline conversion action called "Qualified Lead" set-up in Google ads that is getting the information from a Google sheet. My client is onboarding to Hubspot. Can I switch the offline conversion action source from Google sheet to Hubspot without missing a beat? OR by making the shift to Hubspot, i have to make a new conversion action in Google Ads?

If the former, what is the process to do that?

You don’t need to create a new conversion action in Google Ads. You can continue using the same “Qualified Lead” conversion action and simply switch the data source from Google Sheets to HubSpot.

Here’s the process:

1. Connect your Google Ads account with HubSpot (Settings → Marketing → Ads → Connected Accounts).
2. In HubSpot Ads settings, choose which lifecycle stage(s) (e.g., Qualified Lead) you want to sync as offline conversions.
3. Map HubSpot’s “Qualified Lead” stage to the existing Google Ads conversion action (make sure the naming matches exactly).
4. Once set up, HubSpot will automatically push these conversions into Google Ads, and you can stop uploading via Google Sheets.

✅ This way, you keep all historical data under the same conversion action and don’t “miss a beat.”
If you prefer a clean break, you can create a new conversion action — but it isn’t required unless you want to separate old vs. new tracking.

Hey @UCL - thanks so much for posting in the Community!

I'd like to tag in some Google Ad experts to see if they have any insight for us! @beeginman, @Bryantworks, and @RomyFuchs1 - any thoughts on whether or not @UCL can switch the offline conversation action source from Google sheet to HubSpot without missing any data?
