This template starts when you POST a question and a spreadsheet id to a Latenode webhook.
Google Sheets reads the tab, JavaScript builds a prompt from those rows, and ChatGPT answers in plain language. Connect Google Sheets. ChatGPT is a Latenode AI step, so you do not paste an OpenAI key.
Latenode bills workflow runtime in CPU seconds. The first 10,000 CPU seconds are free each month, then usage follows pay-as-you-go CPU-second pricing. Plug-and-Play (PnP) AI nodes are billed separately—each PnP token is $1 USD, charged pay-as-you-go at vendor cost plus a small processing fee, with no API keys required.
