Here's how to use it:\n\n1. Open the `Google Sheets` node and add a credential (or disabled the node)\n2. Click the `Execute Workflow` button, then double click the nodes to see their input and output data\n\n### To customize this template to you needs:\n1. Swap `When clicking \"Execute Workflow\"` and the `HTTP Request` node with an App trigger. If we don't have a Native app trigger, just replace `When clicking \"Execute Workflow\"` with a [Schedule trigger](https://docs.n8n.io/integrations/builtin/core-nodes/n8n-nodes-base.scheduletrigger/).\n2. Disable or remove parts of the workflow that are not relevant to your usecase.\n4. Activate the workflow \n"},"typeVersion":1},{"id":"426c8cce-0af6-4c9a-9702-9695093fe7fd","name":"Google Sheets","type":"n8n-nodes-base.googleSheets","position":[720,120],"parameters":{"columns":{"value":{},"schema":[{"id":"id","type":"string","display":true,"removed":false,"required":false,"displayName":"id","defaultMatch":true,"canBeUsedToMatch":true},{"id":"status","type":"string","display":true,"required":false,"displayName":"status","defaultMatch":false,"canBeUsedToMatch":true},{"id":"name","type":"string","display":true,"required":false,"displayName":"name","defaultMatch":false,"canBeUsedToMatch":true}],"mappingMode":"defineBelow","matchingColumns":["id"]},"options":{},"operation":"append","sheetName":{"__rl":true,"mode":"list","value":"gid=0","cachedResultUrl":"https://docs.google.com/spreadsheets/d/1fAy_eUTZqaUBnCHTvF7F-VCu0zqlGlupgcAdL68UuJA/edit#gid=0","cachedResultName":"Sheet1"},"documentId":{"__rl":true,"mode":"list","value":"1fAy_eUTZqaUBnCHTvF7F-VCu0zqlGlupgcAdL68UuJA","cachedResultUrl":"https://docs.google.com/spreadsheets/d/1fAy_eUTZqaUBnCHTvF7F-VCu0zqlGlupgcAdL68UuJA/edit?usp=drivesdk","cachedResultName":"Sync data from one app to another [one-way sync] (Destination example)"}},"credentials":{"googleSheetsOAuth2Api":{"id":"uJ1SWmfKH3MikNyZ","name":"Google Sheets account 2"}},"typeVersion":4},{"id":"5886f624-ab5a-4cd2-be2b-b166f617f77c","name":"Set","type":"n8n-nodes-base.set","position":[720,480],"parameters":{"values":{"string":[{"name":"Full Name","value":"={{ $json.results[0].name.first }} {{ $json.results[0].name.last }}"},{"name":"Country","value":"={{ $json.results[0].location.country }}"},{"name":"email","value":"={{ $json.results[0].email }}"}]},"options":{},"keepOnlySet":true},"typeVersion":2}],"connections":{"Set":{"main":[[{"node":"Spreadsheet File","type":"main","index":0}]]},"HTTP Request":{"main":[[{"node":"Google Sheets","type":"main","index":0},{"node":"Set","type":"main","index":0}]]},"When clicking \"Execute Workflow\"":{"main":[[{"node":"HTTP Request","type":"main","index":0}]]}}}
