When you copy and paste data from Google Sheets into Google Slides, you can create a link that can be updated at any time to show the latest data from the source you copied the information from. This allows you to keep your data synchronised across all files that the data is displayed in.
You can copy data from Google Sheets onto a Google slide as follows:
In the sheet, select all data you wish to copy to Google Slides
Click on the Edit menu and choose Copy or press Ctrl C
In Google Slides, choose the slide you wish the paste your data onto
Click on the Edit menu and choose Paste or press Ctrl V
Choose to paste a link to the original sheet, or to paste unlinked, which will not update the data on the slide if the original sheet changes
Click on Paste
The data will be pasted onto the slide and show a Link icon when the data is selected. Click on this icon to see options to open the data source, unlink the data or view all linked objects in the presentation.
Although you can copy and paste text and images from Google Docs to Google Slides, you cannot currently link data to Google Docs, so that the slide updates if the original document changes.
If you have created a chart in a Google Spreadsheet, you can copy the chart into a presentation as required. Once pasted into a presentation, the chart can be moved or resized as required.
In the sheet, click on the chart you wish to copy
Click on the ellipses in the top-right corner of the chart window
Choose Copy Chart
Open the presentation you wish to paste the data into
Click on the Edit menu and choose Paste or press Ctrl V
Choose to paste a link to the original sheet, or to paste unlinked, which will not update the chart if the original sheet changes
Click on Paste
You can also add a chart to a presentation using the Insert, Chart, From Sheets command.
