The Scenario
Your client rebranded last month. They were acquired, changed their company name, updated their domain. You're the executive assistant who manages the executive's Google Contacts, and there are 90 contacts at that client whose Organization field still shows the old name. You have the mapping in a Google Sheet — old email in column A, new company name in column B.
The contacts exist in Google Contacts already. They just need one field updated across all 90 records.
The bad version:
- Search Google Contacts for each email address one at a time, open the record, click Edit, change the Organization field, save, go back to the search bar, type the next email
- Export all contacts to CSV, edit the Organization field for those 90 rows in Excel, delete the rest, and attempt a CSV re-import — which will create 90 duplicate records instead of updating the existing ones
- Write down the resource names for each contact by hand from the URL bar, build a spreadsheet of API calls, and try to figure out the People API batchUpdateContacts endpoint from the documentation
The last option is technically correct. It's also a full afternoon and requires API knowledge you may not have. The first option takes three hours minimum. The second creates a cleanup problem worse than the original.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It can match contacts by email address, find them in Google Contacts, and update a specific field across all matched records in one operation.
Search Google Contacts for each email in column A of my "Rebrand Updates" sheet, update the Organization field to the value in column B for each match, and process all rows in one pass — write "updated", "not found", or the error to column C
What You Get
- Each email in column A looked up against Google Contacts
- Organization field overwritten with the value from column B for every matched contact
- Column C written back with "updated" for each successful change, "not found" for emails that didn't match any contact, and the error message for any that failed
- No duplicates created — the existing records are updated in place
What If the Data Is Not Quite Ready
You need to update two fields at once — Organization and Job Title — and they're in different columns
For each row in my "Rebrand Updates" sheet where column A is an email address, find the matching Google Contact and update both the Organization field to column B and the Job Title field to column C — write the result to column D
Some emails in column A have trailing spaces or inconsistent capitalization that might break the match
Before matching contacts, trim whitespace and lowercase all values in column A of my "Rebrand Updates" sheet, then search Google Contacts for each cleaned email and update the Organization field to column B — write "updated", "not found", or the error to column C
You only want to update contacts where the current Organization field matches a specific old value
For each email in column A of my "Rebrand Updates" sheet, find the Google Contact and only update the Organization field to column B if the current Organization field contains "Acme Corp" — skip contacts where the Organization already shows something else, and write the action taken to column C
The sheet has 300 rows but you want a full audit: old value, new value, status
For each email in column A of my "Rebrand Updates" sheet, fetch the current Google Contact and write the current Organization field to column B, then update it to the value in column C — write "updated", "skipped – already correct", "not found", or the error to column D, and write the timestamp of the update to column E
One prompt captures the before state, makes the update, and logs the outcome — no separate audit step needed.
