Question details
The user needs to understand why adding Excel charts makes a presentation file extremely large and how to reduce the file size.

- Scenario
- Adding or copying Excel charts into a PowerPoint presentation.
- Observed behavior
- The presentation file size grows significantly because embedding even a single chart includes a full, hidden copy of the entire source Excel workbook.
Determine if you still need to update the chart data in the future, as this will dictate whether you should convert the charts to static pictures or re-insert them as linked data.
Ungroup Embedded Charts to Convert to Pictures
Use this method if the chart data is finalized and you no longer need to edit the underlying Excel numbers.
When a chart is embedded, the presentation saves the entire source Excel workbook inside the file. Ungrouping the chart permanently strips away the hidden Excel workbook data and converts the chart into a lightweight metafile picture, which drastically reduces the presentation size.
Open your presentation and click on the embedded Excel chart that is causing the large file size.
Right-click the selected chart, hover over 'Group' in the context menu, and click 'Ungroup'.
A prompt will appear warning you that this is an imported picture and asking if you want to convert it to a Microsoft Office drawing object. Click 'Yes'.
Repeat this process for any other embedded Excel charts in your presentation to remove all hidden workbook data.
Re-insert Charts Using the Link Option
Use this method if you still need the chart to update automatically when the original Excel file is modified.
Prevent Large Presentation Files with WPS Office
WPS Presentation allows you to seamlessly insert Excel charts with granular control over embedding, linking, or pasting as pictures, helping you maintain optimal file sizes.
- 1. Open files side-by-side: Open both your presentation and spreadsheet using WPS Office's convenient tabbed interface.

Frequently Asked Questions
Why does embedding just one cell or chart make the file so large?
When you use the 'Embed' option, the presentation software doesn't just copy the selected chart or cells. It saves a complete, hidden copy of the entire source Excel workbook within the presentation file. If the original workbook is large, your presentation file size will increase by that exact amount for every embedded instance.
What is the difference between embedding and linking a chart?
Embedding stores the actual source file inside the presentation, increasing file size but making it standalone so it can be shared easily. Linking only stores the visual and a reference link to the external file, keeping the presentation small but requiring the external Excel file to remain in the same location for updates to work.
Can I compress the presentation without deleting my embedded charts?
While you can use built-in image compression features to reduce the size of photos and standard pictures in your presentation, this will not affect the size of embedded Excel workbooks. To reduce the file size caused by Excel data, you must either link the charts instead or ungroup them to convert them to pictures.
