I stopped copying spreadsheet data into ChatGPT.
Google Sheets has Gemini built in. Click "Ask Gemini" in the top right corner.
It analyzes your data, creates charts, summarizes findings.
I asked it to rate customer seriousness on a 1-5 scale. It asked clarifying questions, built logic from my data, and inserted a new column.
No copy-pasting. It reads your spreadsheet and acts inside it.
Try the Gemini button before opening a separate AI tool.
