1. Head over to Glide and log in.
2. Click "New Project" to start a fresh app.
3. Choose "Apps" under "New Project".
4. Pick your data source (Google Sheets, Glide Table, or Excel).
5. Give your project a name and hit “Create”.

1. In your data source (Google Sheets, Glide Table, or Excel), create a new sheet or table.
2. Name the first column "Text to Encode".
3. Name the second column "QR Code" – this is where the URL for the QR code image will go.

1. In the "Text to Encode" column, add some sample text. For example: \
   • "Hello, World!"
   • "Visit Glide"
   • "Sample Text"

1. Go back to Glide and find your new project.
2. It should automatically detect your data source and show the columns you made.
3. Click on the "Layout" tab to start designing your app's interface.

1. Add a "List" component to show the rows from your data source.
2. Click on "List" and choose the source sheet or table.

1. Click the "+" icon (Add Component) and pick the "Image" component.
2. Put the "Image" component inside each list item.
3. Set the "Image" component to use the value from the "QR Code" column.

1. Open your data source (Google Sheets or Glide Table).
2. In the "QR Code" column, use this formula to generate the QR code URLs:

   =IMAGE("https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=" & ENCODEURL(A2))
   

   Replace A2 with the cell reference of the "Text to Encode" column.
3. This formula uses the api.qrserver.com service to create QR codes.

1. Save your data changes in your spreadsheet app.
2. Go back to Glide and make sure it's syncing with your updated data source.
3. The QR codes should now show up for each list item.

1. Customize the look and features of your app as you like.
2. Once you're happy with the design, click "Publish" to make your app live.

This guide walks you through creating a QR code generator in Glide, from setting up your data to generating QR codes with an external API and displaying them in your app.
