How to connect the Companion App to your Ultimate Envelopes Sheet. Perform this setup from a desktop browser — you’ll only need to do it once.

Step 1: Open the Apps Script Editor

Open the Apps Script editor from your UE Sheet (Extensions → Apps Script).

Extensions menu open, showing the Apps Script option
Extensions → Apps Script

Step 2: Start a New Deployment

In the top right, click Deploy → New deployment.

Deploy menu open, showing the New deployment option
Deploy → New deployment

Step 3: Deploy

Name the deployment in the Description field, then click Deploy.

Name the deployment and click Deploy

Step 4: Authorize the Script

You’ll be asked to authorize the script — click Authorize access.

Step 5: Approve Access

Click Advanced, then click Go to UE Companion (unsafe). This warning appears because the script isn’t published on the Google Marketplace — Ultimate Envelopes never has access to your data, and everything stays on your own Google Drive.
