Google Sheets

B1 Export is the official Google Sheets add-on for B1.church. It adds a sidebar to any spreadsheet that exports People, Donations, Groups, or Attendance from your B1 church into named tabs — on demand, with one click. The add-on runs entirely inside the user's Google account; nothing about it touches ChurchApps' servers beyond the read-only API calls each export makes.

Before You Begin

  • A Google account with edit access to the spreadsheet you want to export into
  • A church admin (or someone with read access to the data you want to export) able to mint a B1 API key
  • The B1 Export add-on installed from the Google Workspace Marketplace

What It Exports​

Menu itemSheet tabData
Export PeopleB1 PeopleID, Display Name, First, Last, Email, Membership Status
Export DonationsB1 DonationsID, Person ID, Date, Amount, Method, Batch ID
Export GroupsB1 GroupsID, Name, Category, Member Count
Export AttendanceB1 AttendanceID, Person ID, Visit Date, Service ID, Group ID

Each export replaces the contents of its named tab — re-running an export gives you a fresh snapshot, not appended rows. Other tabs in the spreadsheet are untouched.

Setup​

1. Create a B1 API key with the right scopes​

  1. In B1Admin go to Settings → Developer → API Keys.
  2. Click New API Key, name it "Sheets Export", and grant the read scopes for whatever you plan to export:
    • people:read for the People export
    • donations:read for Donations
    • groups:read for Groups
    • attendance:read for Attendance
  3. A key that only does exports does not need settings:write — that scope is only for connectors that register webhooks (Zapier / Make). Keep this key narrow.
  4. Save and copy the cak_… key.

2. Install the add-on​

  1. Open the spreadsheet you want to export into.
  2. Extensions → Add-ons → Get add-ons.
  3. Search for B1 Export and install it. Google asks you to grant access to your sheets and to external HTTP (so the add-on can call the B1 API).

After installation, a B1 Export entry appears under the Extensions menu of every spreadsheet you open with this Google account.

3. Connect the key​

  1. Extensions → B1 Export → Connect… (or B1 Export → Connect… from the menu bar after the first open).
  2. Paste the API key into the sidebar, leave the Base URL as https://api.churchapps.org (unless you're testing against staging), and click Save.
  3. Click Test Connection — a green "Connection OK" confirms the key works.

The key is stored in per-user properties (PropertiesService.getUserProperties()) — it's tied to your Google account, never written into the sheet, and never visible to other editors of the spreadsheet.

Running an Export​

Either:

  • From the menu — Extensions → B1 Export → Export People (or Donations / Groups / Attendance)
  • From the sidebar — open the sidebar (Connect…) and click the appropriate dataset button

A toast confirms when it's done — "N row(s) written to 'B1 People'."

Building Reports On Top​

The exported tabs are plain Google Sheets data. Build your own analytics on referencing tabs:

  • A summary tab with =SUMIF('B1 Donations'!E:E, "card", 'B1 Donations'!D:D) to total card gifts
  • A filtered view of just members with =FILTER('B1 People'!A:F, 'B1 People'!F:F = "Member")
  • A chart of attendance trends pulling from B1 Attendance

Re-running the export refreshes the underlying tab; your formulas update automatically.

Scheduling Recurring Exports​

The add-on is on-demand by default. For weekly or monthly exports, use Apps Script's built-in time-driven triggers:

  1. Extensions → Apps Script in the spreadsheet (this opens the add-on's bound script).
  2. Click the ⏰ Triggers icon in the left sidebar.
  3. Add Trigger for exportPeople (or any export function) — choose Time-driven, Week timer, e.g. Every Monday 6am.

The export runs in the background under your Google account. If the API key is rotated or revoked, the trigger emails you the next time it fails.

Permissions & Privacy​

  • The add-on requests only spreadsheets.currentonly (it can only touch the spreadsheet it's open in) and script.external_request (so UrlFetchApp can call the B1 API). It does not see your Drive, Gmail, or other Google data.
  • The B1 API key is stored per-user — other editors of the same spreadsheet cannot see it.
  • All B1 API calls are made over HTTPS with Authorization: Bearer cak_….

Troubleshooting​

  • "No API key set" — open Extensions → B1 Export → Connect… and paste the key.
  • "B1 rejected the API key (401)" — the key was revoked or is wrong. Re-mint and re-paste it.
  • "This API key lacks permission for /giving/donations (403)" — the key doesn't have donations:read. Update the key's scopes in B1Admin.
  • Sheet doesn't refresh after running — make sure you're looking at the correct tab name (B1 People etc.). The export creates the tab if it didn't exist.
  • "Quota exceeded" — Apps Script imposes per-user daily quotas on UrlFetchApp (typically thousands of calls per day). A large church with many records may need to split exports across multiple days or use Make / a custom integration for high-volume sync.

Customising the Add-On​

The add-on is open source — the Apps Script project lives in the B1Integrations/GoogleSheetsAddon/ repo. If you want a column we don't export, an extra dataset, or a different output format, open an issue or PR there.
