    HOW DATAHASH SETS IT UP

    From kickoff to verified events.

    1. Connect

      Read-only access to the Excel workbook you name, mapped to Meta's Offline Conversions API and tuned for Meta's 62-day event window.

    2. Map

      Columns from your Excel workbook rows align to Meta's Offline Conversions API in the visual mapper, hashed as the file lands and checked for Meta's 62-day event window.

    3. Deliver

      Each time a new file lands, Signals reads your Excel workbook rows and credits dealer, branch, and phone sales to the Meta campaigns behind them, processes only the newly dropped file, with Meta's 62-day event window watched in the debugger.

    WHAT YOU GET

    What changes when the CSV goes away.

    Capability Manual CSV upload Datahash
    Reporting Offline sales sit in a separate export, reconciled by hand. Revenue counted in the same Offline CAPI reporting as web conversions.
    Deduplication A re-uploaded file risks counting the same conversion twice. Deduped delivery, so a resent record never counts as a second conversion.
    Match visibility Match quality is a guess until the numbers look off. Match rate reported per upload, tied to the source event set that produced it.
    Effort and latency An analyst exports and uploads on a manual cadence. Server-side and automatic the moment Microsoft Excel records the event.

    FAQ

    Asked on almost every call.

    How often does the Microsoft Excel Meta Offline CAPI sync run?

    You set the cadence, from near-real-time to a nightly Microsoft Excel sync of your Excel workbook rows into Meta. Since Signals processes only the newly dropped file, in-store and phone revenue joining Meta's optimization loop keeps pace and finance and ops teams working in Excel watch Meta's 62-day event window. One scoped connection sets it up, cadence adjustable later.

    What match rate should a Microsoft Excel-sourced Meta Offline CAPI batch expect?

    Match rate follows identifier coverage in your Excel workbook rows, which finance and ops teams working in Excel control, not Microsoft Excel itself. A record with a current hashed email or phone matches for Meta; one missing both cannot. First-run feedback from Offline Conversions API pinpoints Meta's 62-day event window, the number finance and ops teams working in Excel tune against.
