{viewfile} macro is no longer available from the list of available macros and existing viewfile macro can't be edited/updated.

Also, for existing {viewfile}

macro, in an Edit mode, when you choose the attachment it says: "(Not found)" and do not show the list of attachments from the specific page. See screen shot:

Workaround:

Download and install Confluence Source Editor plugin through UPM. Next, go to the page which has the

{viewfile} macro, edit the page, on the editor you'll see this [<>] button in between 'binocular' button and the [?] button, click on it and a window will pop-up and you'll get something like this:
You may edit this specific line:
to
and then click 'Apply'. This should transform the {viewfile}

macro to

{viewxls}. However, I'm afraid this still has to be done manually on each affected {viewfile} macro.

OR you can also insert {viewxls}

macro into Confluence page using Insert > Wiki Markup. The file will be displayed fine in Confluence page but still can't be successfully edited/updated.

{viewxls}

,

{viewdoc}

,

{viewppt}

macros are working as expected.
