CKEditor copy from word/Excel from other source and paste on editor format not preserving

[sharan]

While copying from source for example word(Might be any source) with Time new Roman 12 to CKEditor same format is not maintaining

Have you set both below options to false:
​http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-pasteFromWordRemoveFontStyles
​http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-pasteFromWordRemoveStyles

Perhaps there are some rules missing for ACF? You could disable it for tests to find out if this is the reason of your problems and then configure it properly. Please see: ​http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter

NOTES:

• Please remember that result will never be 1:1. We have desktop application with HTML like language and application working inside browser where there is pure HTML. CKEditor makes it best to translate the information send from Word through the clipboard and many times it needs to come to an agreement. In those cases we prioritize semantics instead of formatting.
• Please upgrade to latest editor 4.4.5 as version 3.6.4 is no longer supported.
