In this example we're saving a new qualified lead to a Google Sheets file. Here's how you can test the template:\n\n1. Duplicate our [Google Sheets](https://docs.google.com/spreadsheets/d/1gVfyernVtgYXD-oPboxOSJYQ-HEfAguEryZ7gTtK0V8/edit?usp=sharing) file\n2. Double click the `Google Sheets` node and create a credential by signing in.\n3. Select the correct Google Sheets document and sheet.\n4. Click the `Execute Workflow` button and double click the nodes to see the input and output data\n\n### To customize it to you needs, just do the following:\n1. Enable or exchange the `Postgres trigger` with any service that fits your use case.\n2. Change the `Filter` to fit your needs\n3. Adjust the Google Sheets node as described above\n4. Disable or remove the `On clicking \"Execute Node\"` and `Code` node\n"},"typeVersion":1},{"id":"8bc7439e-d814-4960-8b75-fc77805f74c7","name":"Sticky Note","type":"n8n-nodes-base.stickyNote","position":[460,380],"parameters":{"width":344,"height":562,"content":"### 1.
