Hi All,
using Office 2016
I am trying to compare 2 documents and expecting to be same but they are shown Revisions. Steps to do
1. Open Word
2. Insert > chart > column (just use the default data and close Excel)


3. Save file as 1.docx and close word
4 . Repeat steps 1-2 and save the file as 2.docx

Now Open Word > Review >Compare
use 1.docx and 2.docx
expecting them to be same and 0 revisions. I get 2 revisions

Is this a bug? your help appreciated.

Presumably, just some undocumented 'feature' of how the compare function works. Even in Word 2010, if you use File Explorer to make a copy of 1.docx, then compare that with the original, you'll get 1 change recorded. Evidently the two changes have something to do with the time-stamp difference.

I understand your frustration with the issue you're encountering. What you're experiencing is not necessarily a bug, but rather a common scenario when dealing with autogenerated content like charts in Word.
When you insert a chart in Word, it embeds an Excel worksheet to store the chart data. Each time you create a new chart, even if it looks identical, Word generates a unique underlying data structure. This unique structure includes metadata and possibly slight differences in how the chart data is stored internally.
