How to compare two Pages documents

I worked for a long time on a Pages document:

file.1.pages.

Since I didn't plan to make many modifications, I didn't activate

Edit > Track Changes

silly me 😊!

I saved the modified Pages document with a new name:

file.2.pages

Now I would like to check I didn't forget a key point or made any error during my

modifications. Well I would like to review and check all the modifications I made.

How may I compare

file.1.pages

and

file.2.pages

This isn't a comparison I can deal with manually:

• too much text,
• too many small spelling fixes,
• many unsignificant formatting changes.

Wasting a lot of time within the over long menus of Pages, I didn't find anything that

could help me solve this very basic function of a text editor.

I think I should be blind not to see this elementary function.

Silly me 😊!

Next I searched on the web for any receipe to achieve it, and with the problem

caused by the name of this software ( Pages ) I just found 2 tons of irrelevant answers

and nothing simple, easy to use.

Note: I am at ease with all the command line tools, and would appreciate such a way to deal with

this function. For example, with:

vi

this is trivially achieved with:

diff file.1 file.2

within less than 2 seconds to type this command line.

And in a modern IT world, this should be easier with a graphical user interface in a tool like Pages.

Of course his is a question independant of any version of hardware and macOS.

I filled the field asked to feed the robot, but it's irrelevant 😊.
