The Scenario
You are a sales ops analyst. A rep left the company yesterday. She owned 250 contacts and 40 accounts in Apollo. Her replacement started Monday. Your job is to reassign everything before the team notices the orphaned records.
The mapping is in an Excel workbook on SharePoint: column A has Apollo contact IDs, column B has the new owner's email address in the Contacts tab. A second tab has account IDs in column A and new owner IDs in column C.
The slow version:
- You open Apollo, search for the first contact by ID, open the record, click Reassign, select the new owner, save
- You do this 250 times
- You forget to switch to the Accounts tab because by contact 200 you are on autopilot
- Two days later a deal is missed because three accounts are still showing the departed rep as owner.
The fast version is one prompt per tab.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook that reads the ID-to-owner mapping and pushes the reassignments to Apollo without you opening a single contact record.
Open the SheetXAI sidebar and type:
Update the owner of every Apollo contact in column A of the Contacts tab (contact IDs) to the user whose email is in column B. Write "Reassigned" or the error message into column C for each row.
Then for the Accounts tab:
Bulk-update Apollo account ownership: for each account ID in column A of the Accounts tab, reassign it to the Apollo user whose ID is in column C. Write the result status into column D.
SheetXAI processes both tabs, calls Apollo's update API for each record, and writes the outcome back per row.
What You Get
Contacts tab:
- Column A — contact IDs, unchanged
- Column B — new owner email, unchanged
- Column C — "Reassigned" or the specific error per row
Accounts tab:
- Column A — account IDs, unchanged
- Column C — new owner IDs, unchanged
- Column D — "Reassigned" or the specific error per row
Row-level status means you have an audit trail for the ops handoff.
What If the Mapping Is Not Quite Ready
Rep departure maps are assembled in a hurry. SheetXAI handles gaps and the reassignment together.
When the new owner column has emails for some rows and names for others
The mapping was built by two different people and column B has a mix of email addresses and full names.
For rows in column B of the Contacts tab that contain an "@" sign, treat the value as an email. For rows that do not, treat it as a full name and look up the Apollo user ID by name. Then reassign each contact in column A to the resolved owner and write status into column C.
When some contacts should go to one rep and others to a second rep based on territory
Territory is in column C of the Contacts tab.
For each row in the Contacts tab, read column C for territory. If column C is "NA," reassign the contact ID in column A to the Apollo user whose email is in cell E1. If column C is "EMEA," reassign to the user in cell F1. Write the reassignment status into column D.
When you want to reassign only contacts in specific stages
Only contacts in Prospecting or Qualified need immediate reassignment.
For each row in the Contacts tab, check column D for the contact's current Apollo stage. If the stage is "Prospecting" or "Qualified," reassign the contact in column A to the owner in column B and write "Reassigned" into column E. For all other stages, write "Deferred" into column E and skip the update.
When the full cleanup — deduplication, stage filtering, owner resolution, and reassignment — needs to happen in one shot
The mapping workbook was assembled from three different exports and has duplicates, missing owner emails for some rows, and contacts in stages you do not want to touch yet.
Deduplicate column A of the Contacts tab, keeping the last occurrence of each contact ID. For rows where column B is blank, look up the correct new owner email from the Ownership Fallback tab using the territory value in column C. Filter to rows where column D stage is Prospecting or Qualified. Reassign all remaining contacts in Apollo using column A for the ID and the resolved owner email for the new owner. Write status into column E.
The pattern: cleanup, filtering, and bulk reassignment are one prompt. The status column gives you the paper trail.
