I do not think what you are trying to do, is a possibility with EPPlus. EPPlus provides only that functionality that excel supports by itself and Excel itself does not support viewing the header and footer in edit mode. This is what the documentation about Headers and footers has to say regarding this. This is applicable to Excel for Microsoft 365, Excel 2019, Excel 2016, Excel 2013, Excel 2010, Excel 2007, Excel Starter 2010.

Headers and footers are displayed only in Page Layout view, Print Preview, and on printed pages.

Further if you take a look at the source of the ExcelHeaderFooter class, there is no provision that deals with viewing in Page Layout view or anything related (you can set have printer settings set on the worksheet though).

You can accommodate the Title in the first row with the below lines of code

I rearranged your code. some variables were defined before they were used.

Have A look at dateparser library in python :

https://dateparser.readthedocs.io/en/latest/

It will parse the above mentioned dates along with searching the dates in sentences, supporting different languages etc.

Now the problem that I see is that you're trying to init a new tinymce editor when your data changes, but the editor already exists and therefore the editor.on('init'...) is not called again. The problem only occurs when you switch to another Email template after tinymce was initialized already, but works fine when the first row is selected.

So basically calling tinymce.init the first time works fine, calling it again later does not. The MailTemplatesComponent stays the same when switching to another row, it's not changing, only the data in it, so its reference to editor will also be kept and not destroyed, which is why calling init again is probably not working. tinymce probably thinks, hey I already have initialized that, I don't have to do it again.

Here are two possible solutions I see. First one is to remove the editor on every ngOnChanges and reinit again.
