The Scenario
You are a data ops analyst. Your team has accumulated 300 PhantomBuster lead IDs that are stale: people who bounced, who asked to be removed, or whose roles were scraped over a year ago and no longer reflect reality. They need to be deleted from PhantomBuster org storage.
The IDs are in the LeadObjectID column of an Excel workbook. Your manager wants them gone before the new quarter starts Monday.
The bad version of Friday afternoon:
- You look for a bulk delete option in PhantomBuster and find a CSV-based import
- The import format does not match the column structure in your workbook
- You create a staging tab, export the IDs to a properly formatted CSV, and upload it
- PhantomBuster confirms 261 deletions but gives no detail on the 39 that failed
- You spend an hour cross-referencing the uploaded CSV against the PhantomBuster storage list to identify the gaps
- You find 12 of the 39 failures were already deleted by someone else last week, and you wasted an hour checking them.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook that reads the LeadObjectID column, calls PhantomBuster's delete endpoint for each ID in batches, and writes the result back per row.
Open the SheetXAI sidebar and type:
Read the Excel column 'LeadObjectID', delete each corresponding lead object from PhantomBuster storage, and write DELETED or ERROR into the adjacent column.
SheetXAI processes each ID, calls the delete endpoint, and writes DELETED or ERROR next to every row. The 39 that fail show ERROR immediately, with no manual cross-referencing needed.
What You Get
A completed deletion run with per-row status written into the column adjacent to LeadObjectID:
- DELETED — lead object removed from PhantomBuster storage
- ERROR — deletion failed (not found, already deleted, or API error)
Count the DELETED rows to confirm the purge is complete. Filter the ERROR rows to decide whether they need manual follow-up or can be ignored because they were already cleaned up. Send the workbook to your manager as the audit record.
What If the Data Is Not Quite Ready
Stale lead workbooks are not always clean lists. SheetXAI handles the edge cases before deleting.
When some IDs might already have been deleted
The workbook was assembled from two sources and a previous cleanup pass may have already removed some of these leads.
For each ID in the LeadObjectID column, first check if the lead exists in PhantomBuster. If it exists, delete it and write DELETED in the adjacent column. If it does not exist, write ALREADY REMOVED. Process in batches.
When you need a deletion timestamp for compliance
The compliance team needs to know the date and time each lead was removed, not just whether it was.
Delete each lead ID in the LeadObjectID column from PhantomBuster org storage in batches. Write the deletion status in the next column and the current date and time in the column after that for every DELETED row.
When the workbook has duplicate IDs from two source lists
The list was compiled from two exports and some IDs appear twice. Deleting the same ID twice returns an error on the second attempt.
Before deleting, deduplicate the LeadObjectID column, keeping only the first occurrence of each ID. Mark the duplicate rows with DUPLICATE in the adjacent column and skip them. Then delete all unique IDs from PhantomBuster org storage in batches and write DELETED or ERROR for each.
When you need to purge, log, and produce a final audit summary before Monday
The manager needs to show the audit trail to the compliance team Monday morning.
For each ID in the LeadObjectID column, delete the corresponding lead from PhantomBuster org storage in batches. Write DELETED or ERROR in the next column. Write the current date and time in the following column for each DELETED row. After all rows are processed, write a summary in cell E1: "Total: 300 | Deleted: X | Errors: Y | Already removed: Z".
The pattern: delete, log every result, and produce the audit document in one prompt. The compliance record is in the workbook before you close it.
Try It
Get the 7-day free trial of SheetXAI and open any Excel workbook with PhantomBuster lead IDs, then ask it to run the deletion and write back the status. The PhantomBuster integration is included in every SheetXAI plan. For related workflows, see how to export all PhantomBuster leads to Excel first or the PhantomBuster in Excel overview.
