The Scenario
You are an operations coordinator at a real estate agency. The quarterly postcard drop is in one week. You have 600 prospect records in a Google Sheet: first name in column A, last name in column B, address line in column C, city in column D, state in column E, ZIP in column F, and email in column G.
Every one of those contacts needs to be in PostGrid before the campaign team can start building the mailing batches. You also have 40 records from last quarter marked "Churned" in column H, and those need to be removed from PostGrid so they do not receive mail.
The PostGrid dashboard does not have a bulk import. It takes contacts one at a time or via API.
The slow version:
- Export the sheet as CSV
- Ask your developer to write a bulk import script
- They are out this week
- You import the contacts by hand starting at row 1
- You quit somewhere around row 80 and the campaign starts without a full contact list.
The fast version is one prompt and SheetXAI handles the import and the deletions.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads your prospect sheet and calls PostGrid's contacts endpoint for each row, writing the returned contact IDs back so you have a complete cross-reference.
Open the SheetXAI sidebar and type:
Create a PostGrid contact for each row in the 'Prospects' sheet where column H does not say 'Churned'. Use first name from column A, last name from column B, address line from column C, city from column D, state from column E, ZIP from column F. Write the returned contact ID into column I.
SheetXAI filters the rows, skips the churned ones, calls PostGrid's contact creation endpoint for each active prospect, and writes each returned contact ID back to column I.
What You Get
560 PostGrid contacts created, cross-referenced in the sheet:
- Contact ID — written to column I for every imported row
- Churned rows skipped — rows where column H says 'Churned' have no PostGrid contact created
- Cross-reference — column I lets you look up any contact's PostGrid ID from the sheet without logging into PostGrid
The IDs in column I are your sync key. Next quarter when you want to update addresses or delete more churned contacts, you already have the ID in the sheet. No lookup needed.
Want to delete the churned records instead of just skipping them? Add a second instruction: "For rows where column H says 'Churned' and column I has a contact ID, call the PostGrid delete endpoint and write 'Deleted' into column J."
What If the Data Is Not Quite Ready
Merged prospect lists from multiple sources are rarely clean. SheetXAI handles the prep and the import in the same prompt.
When names are in a single full-name column
The export has full name in column A instead of first and last name split into separate columns.
Split the full name in column A into first name in a new column A and last name in a new column B, shifting the existing columns right. Then create a PostGrid contact for each row where column H does not say 'Churned', using the split name and address from columns C through F, and write the contact ID into column I.
When duplicate emails indicate duplicate prospects
Some rows share an email address because the same person submitted the form twice.
Deduplicate the 'Prospects' sheet by the email address in column G, keeping the row with the most complete address data. Then create a PostGrid contact for each remaining row where column H is not 'Churned' and write the returned contact ID into column I.
When you need to delete churned contacts and create new ones in one pass
You have 40 churned records with existing PostGrid IDs in column I that need to be deleted, and 560 active ones that need to be created.
For rows where column H says 'Churned' and column I has a contact ID, call the PostGrid delete endpoint and write 'Deleted' into column J. For all other rows where column I is blank, create a new PostGrid contact and write the returned ID into column I.
When the address data is dirty, duplication is rampant, and you need both creates and deletes
The sheet is a merge of three imports: some duplicate rows, some invalid state abbreviations, some churned contacts with IDs to delete.
Normalize the state abbreviation in column E to the standard two-letter format. Deduplicate by email address in column G, keeping the most complete row. For rows where column H says 'Churned' and column I has an ID, delete the PostGrid contact and write 'Deleted' into column J. For remaining rows where column I is blank, create a PostGrid contact and write the returned ID into column I.
The pattern: one prompt runs the cleanup, the deletes, and the creates in sequence. You get a clean contact list in PostGrid without touching the dashboard.
