AI chart generator

Turn the range into a chart people can read.

Tell Griddy what the data should show, which range to use, how to map categories and series, and where the chart belongs. The result remains an editable chart in Excel or Google Sheets.

Griddy supports common spreadsheet chart types and can create or update chart objects. You should verify the source range, axes, aggregation, and labels.

Chart creation in ExcelReal product demo
Griddy creates several native Excel charts from named source ranges and a prompt that specifies chart type and location.

Concrete chart prompt

“Create a line chart, bar chart, doughnut chart, and stacked area chart on the Charts sheet using the data from the Chart Data sheet. Place them starting at A1, A20, I1, and I20.”

The request names each chart type, source sheet, destination sheet, and anchor cell. A stronger production prompt would also name the exact source range and chart titles.

Expected output

  • Editable chart objects created on the requested report sheet.
  • Separate placements that keep the charts from covering source data or one another.
  • Categories and series mapped from the source ranges.
  • Charts that remain connected to their spreadsheet data.

A chart can be technically correct but misleading. Review the scale, category order, series names, missing periods, and whether the chosen type matches the question.

Workflow

From request to workbook.

  1. 01

    Choose the question

    Decide whether the chart should show a trend, comparison, composition, distribution, or relationship. That question should drive the chart type.

  2. 02

    Name the source

    Specify the exact sheet and range, which column supplies categories, which columns are series, and whether headers are included.

  3. 03

    Describe the chart

    State the chart type, title, placement, legend or label needs, and any series that belong on a secondary axis.

  4. 04

    Inspect the story

    Confirm that labels, units, periods, ordering, and source ranges are correct. Update the existing chart rather than creating a duplicate when refining.

Chart work

Create the object, then refine the story.

Chart generation is a distinct task: the deliverable is a native visualization with a defensible source range and readable mapping, not a generic image.

01

Common chart types

Create bar, column, line, area, scatter, combo, pie, or doughnut charts when the source data supports the selected form.

02

Titles, series, and placement

Name the chart, identify categories and multiple series, choose a sheet and anchor, and place the output away from the source block.

03

Summary first, chart second

Build a pivot or formula-driven summary when raw rows need aggregation before they can support a clear chart.

Review before you rely

Check the data story, not just the styling.

A chart is useful when a reviewer can trace it back to the right data and read the comparison without guessing.

  • Verify the chart range includes the intended headers and every relevant period or category.
  • Check that the X-axis, series, units, and sort order match the analytical question.
  • Avoid pie or doughnut charts when too many categories make composition difficult to compare.
  • If the source is raw transaction data, aggregate it with formulas or a pivot before charting.

FAQ

Before you start.

Does Griddy create an editable chart?

Yes. Griddy creates supported chart objects inside Excel, Google Sheets, or the browser spreadsheet, so the visualization remains connected to its spreadsheet data.

Which chart types can Griddy create?

Supported types include common options such as bar, column, line, area, scatter, combo, pie, and doughnut. Exact options and update behavior vary by spreadsheet platform.

What should I put in a chart prompt?

Name the analytical question, exact source range, category and series columns, chart type, title, destination sheet, and anchor cell. Add label or axis requirements only when they help interpretation.

Can Griddy update an existing chart?

Yes, supported chart update operations are available. Identify the existing chart and state the change so Griddy can refine it instead of creating a second object.
