How to Create Charts in Google Sheets with Gemini (2026)

If you are searching for google sheets ai chart generator, the practical goal is simple: turn selected spreadsheet data into a clear chart without manually building ranges every time.

A reliable workflow is to use Sheet Agent in Gemini AI for Sheets, select the relevant tabs in the UI, then request one chart per prompt.

When this workflow is the right fit

• You need quick visuals for weekly ops, sales, or campaign updates.
• Your data sits across multiple tabs and you want one focused chart.
• You want a repeatable flow that avoids fragile manual range mapping.

Step 1) Prepare clean chart-ready columns

Keep one clear header row and make sure metric columns are numeric (not text like "$1,234" stored as plain text).

1. Keep category/time columns explicit (for example Date, Region).
2. Use consistent metric names (for example Revenue, Orders).
3. Remove fully blank rows before chart generation.

Step 2) Open Sheet Agent and choose source tabs

In Google Sheets, open Extensions → AI for Sheets → Sheet Agent.

1. Click the Sheet selector (the + button in the input row).
2. Tick only the tabs you want to include.
3. Click Apply.
4. Send one concise chart request.

Create one column chart from the selected sheets.
X-axis: Region
Y-axis: Total Revenue
Title: Revenue by Region

Keep it specific and short. One prompt should request one chart.

Step 3) Refine with short follow-up prompts

After the first chart, adjust intent with a short follow-up instead of rewriting everything.

Use a line chart instead. X-axis: Month, Y-axis: Total Orders.

Keep the same data, but create a combo chart for Revenue and Margin %.

Rename the chart title to: Weekly Revenue Trend (Last 12 Weeks).

Step 4) Run a quick quality check before sharing

• Axis sanity: verify the X-axis is category/time, not a metric column.
• Numeric sanity: ensure plotted columns are true numbers.
• Scope sanity: confirm only intended tabs were selected in the Sheet selector.
• Narrative fit: chart title should match your reporting question.

If you need a deeper narrative with actions, run multi-table analysis first, then ask for a chart from the final summary table.
