Question

Is there a TinyMCE plugin that allows to paste a table from MS Excel while also keeping the format of that table?

Partial solution:
So using the paste plugin, you can paste the Excel table onto Word and then from Word paste it onto TinyMCE, which formats correctly. This is not ideal but better than nothing. Still hoping someone has a better solution.

Answer 1

You might want to check out the paste plugin. This plugin needs to be configured properly.
have a look here for the documentation.

EDIT: Example to log the pasted content:

    paste_preprocess : function(pl, o) {
        console.log('Object', o);
        console.log('Content:', o.content);
   }
