I have mat-table with many cells, one of cells is
<img src="data:image/png;base64,iV....">
how to export table to excel file?
I guess easiest way would be to use a dedicated libary for such a thing. E.g https://www.npmjs.com/package/mat-table-exporter
Example: https://stackblitz.com/edit/mte-demo
Seems that it would support output data encoding so you could in theory also export images to excel.
