Merge/Combine Word Documents in Zapier lose formatting

I am using Aspose with Zapier to merge two or more docx files together.
My issue is that when I merge using Zapier then the documents lose certain formatting styles. For example text that has styling with “Heading 1” changes to normal. This causes an issue with the table of contents. Strangely when I use this url https://products.aspose.app/words/merger and merge the same documents the formatting doesn’t get lost.


Please share your sample input documents along with the output document. We will test the scenario and will share our findings with you.

Please find two documents attached to test with.
I noticed when testing that when I merging the documents, the FIRST document in the merge keeps the formatting as expected; however the next documents lose the formating. If you change the order of these 2 documents you will get that result.

We have good news for you. We have fixed the above reported issue. We have introduced the Import Format parameter. Now, you can use ‘KeepSourceFormatting’ or ‘UseDestinationStyles’ formatting properties as per your requirements.

thanks - what is the correct option to use n my case.

I see the options:

It seems like KeepSourceFormatting would be the correct option in my case?


Yes, it looks like KeepSourceFormatting value will be used in your case.
