Charts & tables
How charts and tables are created from your source data
Presentation Maker creates real, editable charts and tables directly from your source data. Unlike basic AI tools that generate static images, you get native PowerPoint charts and tables that you can modify after downloading.
Charts
Supported chart types
| Type | Best for |
|---|---|
| Bar | Comparing categories side-by-side |
| Column | Time series, period-over-period comparisons |
| Line | Trends over time, growth trajectories |
| Pie | Composition, market share, percentage breakdowns |
Charts can be clustered or stacked depending on your data structure. The AI selects the appropriate chart type based on the data and context.
How chart data is populated
When your sources include structured financial data (Excel files, financial models, tables in PDFs), the AI extracts and visualizes it directly:
- Extracts data — Finds relevant numbers in your sources
- Selects chart type — Chooses bar, column, line, or pie based on the data
- Formats axes — Applies display units (thousands, millions, billions) and number formats
- Adds data labels — Includes values on the chart with appropriate formatting
- Applies theme colors — Uses your brand colors for series fills
Fully editable in PowerPoint
When you download your deck, charts contain an embedded Excel workbook. Click any chart in PowerPoint and select "Edit Data" to:
- Update values
- Add or remove data points
- Change series labels
- Adjust formatting
This means you can make last-minute corrections or update figures without regenerating the entire deck.
Axis formatting
Charts automatically format axes based on your data:
| Data magnitude | Display format |
|---|---|
| Thousands | Values shown as "10K", "50K" |
| Millions | Values shown as "10M", "50M" |
| Billions | Values shown as "1.2B", "5B" |
| Percentages | Values shown as "10%", "45%" |
For pie charts, data labels show percentages with proper formatting (e.g., "44.0%" not "0.44").
Requesting charts in your prompt
Be explicit when you want charts:
Include a revenue chart showing the last 4 years of growth. Add a pie chart showing customer concentration by segment.
If you have specific data in your sources, reference it:
Create a financial performance slide using the revenue and EBITDA figures from the Q4 financial model. Show both metrics as a stacked column chart.
Tables
What tables are created for
Tables appear throughout your presentations for:
- Financial summaries — Revenue, margins, key metrics
- Customer lists — Top customers with contract values
- Competitive comparisons — Feature matrices, positioning
- Team rosters — Names, roles, backgrounds
- Timeline milestones — Key dates and achievements
Table features
| Feature | Description |
|---|---|
| Merged cells | Headers and categories can span multiple columns |
| Per-cell formatting | Numbers, percentages, and text formatted appropriately |
| Citations | Individual cells can include source references |
| Character limits | Content is sized to fit the slide layout |
Fully editable in PowerPoint
Tables are native PowerPoint tables—not images. After downloading, you can:
- Edit any cell
- Add or remove rows and columns
- Adjust formatting and colors
- Resize the table
Requesting tables in your prompt
Specify when you need tabular data:
Include a table comparing our top 5 competitors across pricing, features, and market share.
Add a customer concentration table showing our top 10 customers by revenue with contract renewal dates.
Providing good source data
For best results with charts and tables, upload structured data:
Excel files and financial models
- The AI reads Excel files and extracts data for charts
- Clear column headers help the AI understand what each series represents
- Multiple sheets are supported—the AI searches across all tabs
PDF tables
- Tables in PDFs are extracted and can be used for charts or reproduced as tables
- Clean, well-formatted PDF tables work best
Structured text
If you don't have Excel files, provide structured data in your sources or prompt:
Revenue by year:
- 2022: $12.5M
- 2023: $18.2M
- 2024: $28.4M (projected)
Create a column chart showing this growth trajectory.
Limitations
Layout constraints
Charts and tables appear on slides with layouts that support them. Not every slide can contain a chart or table—the AI selects appropriate layouts during planning.
Data complexity
Very complex charts (waterfall, combination charts with multiple axes, Gantt charts) are not currently supported. For these, create the chart manually in PowerPoint after downloading.
Source data quality
Charts are only as good as the data in your sources. If the AI can't find specific figures, it will mark values as "Illustrative" or "TBD" for you to fill in manually.
