The Scenario
You are an outbound sales team lead. The new campaign goes live Monday. You have 300 prospects in a Google Sheet, one per row, with columns for name and phone number.
Every one of them needs to exist as a Synthflow contact before the campaign can be assigned to an agent. Creating them one at a time in the Synthflow dashboard would take hours you do not have.
The bad version of this weekend:
- You find the Synthflow create-contact API endpoint in the docs
- You ask an engineer to write a quick import script
- The engineer is not available until Monday afternoon
- You try to manually create the first 30 contacts through the Synthflow UI
- By contact 8 you have already made two formatting errors on phone numbers
- The campaign launches Monday with 30 of 300 contacts loaded.
The fast version is one prompt on Sunday evening.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet that handles the bulk contact creation loop and writes each returned contact ID back to the row, so you do not need an engineer or an import script.
Open the SheetXAI sidebar and type:
Create a Synthflow contact for every row in this sheet using the name from column A and the phone number from column B. Write the returned contact ID into column C.
SheetXAI iterates through all 300 rows, creates each Synthflow contact, and writes the returned IDs into column C. When it finishes, you have 300 contact IDs in the sheet and the campaign is ready to assign.
What You Get
A completed sheet with 300 contact IDs in column C:
- Column A — prospect name (unchanged)
- Column B — phone number (unchanged)
- Column C — returned Synthflow contact ID, or an error flag for any row that failed
You can see exactly which contacts were created and which were not. If 5 rows failed because of an invalid phone number format, they show an error flag in column C, and you fix just those 5 rows and rerun.
This is the contact provisioning pattern, and it is the reason a bulk task that would take a weekend of engineering work becomes a Sunday-evening prompt.
What If the Data Is Not Quite Ready
Prospect sheets are rarely clean. SheetXAI handles normalization and creation in the same prompt.
When phone numbers have inconsistent formatting
Some numbers have country codes, some do not. Some use dashes, some use dots.
Normalize all phone numbers in column B to E.164 format before creating Synthflow contacts. Then create a contact for each row and write the returned ID into column C.
When some rows already have contact IDs from a previous import
You ran a partial import last week and 80 rows already have IDs in column C. You only want to create contacts for the rest.
Skip any row where column C already has a value. For all other rows, create a Synthflow contact using column A and column B, and write the returned contact ID into column C.
When you need to tag contacts by tier before creation
Your prospect list has a tier column in column D. You want Synthflow contacts tagged by tier so the agent can personalize calls.
Create a Synthflow contact for each row using name from column A and phone number from column B. Add a custom tag for the value in column D as a tier label. Write the returned contact ID into column E.
When you need to create contacts and immediately add them to a campaign
You want zero manual steps between the import and the campaign assignment.
Create a Synthflow contact for each row in this sheet using name from column A and phone number from column B. Write the returned contact ID into column C. Then add each created contact to Synthflow campaign [CAMPAIGN_ID] and write the campaign assignment confirmation into column D.
The pattern: bulk creation is not a script, it is a prompt with a write-back. Three hundred rows, one instruction, full ID tracking.
