How do I export a chart as a png in Excel 2010?
You can't do this directly from Excel; you need to use an external application:
Select the chart, and then copy it to the clipboard (Ctrl-C).
Open a picture editor that supports saving to PNG.
Do a paste in the picture editor (when copying the chart from Excel 2010, it is recognized as a valid picture on the clipboard). The best will be to paste as new image if the picture editor supports that.
Save as PNG.
If you're working within the Office environment you don't need any other software, all you need to do is select & copy your chart then choose the Paste Special option. One of those paste options is PNG. The others include:
- PNG
- JPEG
- GIF
- EMF
- BMP
- Microsoft Office Drawing Object
If you need to export outside of the Office environment, then you can use Office Picture Manager. Just paste your chart inside your My Pictures folder (or whereever is most convenient). My charts paste as PNG by default, but if yours don't, you can choose your image and File>Export and choose your file type, inlcuding PNG, from the list.
There's a free, open-source Excel add-in to accomplish that, "Daniel's XL Toolbox" (https://www.xltoolbox.net).
