Plenty of tools export Klaviyo into a spreadsheet. The direction most workflows actually need — pushing spreadsheet edits back into Klaviyo — is where they stop. SheetPort's write-back closes the loop: select rows in Google Sheets, and they become profile updates or list additions in Klaviyo.
| Action | What happens in Klaviyo |
|---|---|
| Upsert profiles | Each selected row is created or updated as a profile, matched by email. Standard columns (name, phone, location) map automatically; any extra columns become custom properties on the profile. |
| Add to list | Selected rows are added to any Klaviyo list you choose — ready for segments and flows. |
Fix a misspelled property across 2,000 profiles, tag wholesale customers, or backfill a vip_tier field — with fill-down and find-and-replace instead of clicking through profiles one by one.
Compute things Klaviyo can't easily: LTV deciles from your order export, RFM scores, "bought A but never B" flags. Write the result into a column, filter the rows, push them to a list.
Teams already collect signups, event leads and partner lists in spreadsheets. Instead of downloading and re-importing through Klaviyo's CSV wizard, push the rows straight from the sheet.
Because SheetPort also pulls your existing profiles down, you can dedupe and normalize against the real list in the same tab before writing anything back.
Profiles and Lists (key setup guide).email column plus any properties you want set.Klaviyo's own CSV import works, but it means downloading the sheet, walking the upload wizard, and re-mapping columns every single time — and it only covers list imports, not ad-hoc property fixes. If your current routine is export–edit–reimport, the CSV alternative guide covers the full picture, including the pull direction and auto-refreshing reports.
