The Scenario
The event ended Thursday. You are a demand-gen manager who walked out of the conference with 180 badge-scanned emails in an Excel workbook. The SDR team starts sequencing Monday. Every one of those 180 people needs to be in the Attio list "Event Leads Q2" before the weekend.
Adding someone to an Attio list requires knowing their person record ID, which requires looking them up by email. That is a lookup plus a list add, per person, times 180 people. You ran the math and decided not to think about it too hard.
The bad version:
- Copy each email from the workbook, search for the person in Attio, open their record, copy the ID, open the Event Leads Q2 list, click Add Entry, paste the ID. Repeat 179 more times.
- Look for a bulk-add-to-list feature in Attio — find that it works from a filtered view but not from an external list.
- Ask the SDR ops manager to handle it and hear they're swamped with a different launch.
The event was Thursday. Monday's sequencing doesn't move.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. Through its built-in Attio integration it reads each email, finds the person record, adds them to the named list, and logs the result.
Take every email in column A of my Excel sheet, find each person in Attio, and add them to the Attio list with slug 'event-leads-q2'; log the entry ID in column B.
What You Get
- Column B fills with the list entry ID for each person successfully added.
- Emails where no matching Attio person was found show an error note — you can create those records separately or flag for manual follow-up.
- The Attio list reflects all 180 entries once the prompt runs.
What If the Data Is Not Quite Ready
Some contacts don't have an existing Attio person record
For each email in column A, look up the Attio person; if found add them to 'event-leads-q2'; if not found, create a new person record with that email and then add them; write 'added (existing)' or 'added (created)' in column B.
The workbook has first name and last name alongside the email
For each row, find the Attio person by email in column C; if found add them to 'event-leads-q2'; if not found, create the person with first name from column A, last name from column B, email from column C, then add to the list; write the result in column D.
You want to set a list entry attribute for the source event
For each email in column A, find the Attio person and add them to 'event-leads-q2'; set the entry attribute 'source_event' to 'ProductSummit2026'; write the entry ID or error in column B.
Validate emails, create missing records, add to list, set attribute, log in one pass
Validate each email in column A. For valid emails, find or create the Attio person; add to 'event-leads-q2' with source_event set to 'ProductSummit2026'; write 'added' or 'created+added' in column B. Write 'bad email' for invalid rows.
