Thank you for your understanding and continued feedback.

The time for inserting ooxml into the document when using the web version is very slow

Your Environment

Platform [PC desktop, Mac, iOS, Office on the web]: Office on the web and desktop Office
Host [Excel, Word, PowerPoint, etc.]: Word
Operating System: Windows 10 Pro
Browser (if using Office on the web): Chrome Version 101.0.4951.64 (Official Build) (64-bit) / Office Version 2204 Build 16.0.15128.20158 (64 bits)

Expected behavior

We expect that the content would be inserted faster, without stopping the flow of the user.

Current behavior

Right now the insertion takes several seconds. Even if the ooxml inserted is small.

Steps to reproduce

In the script replace "value" with a valid ooxml.

const value = "SOME_OOXML_CONTENT";
Office.onReady(info => {
  Word.run(async () => {
     const selection = context.document.getSelection();
     selection.insertOoxml(value, Word.InsertLocation.after);
  })
});

Videos showing the insertion speed:

• ooxml desktop insertion - normal
• ooxml web insertion - slow

Context

Our application relies heavily on inserting content into the document. Because of this issue, the user experience is worse on the web

Hi @benjamin-almarza, is the performance equally bad for desktop and online?

[benjamin-almarza]

No, it is not. As you can see in the videos I attached. Desktop inserts almost immediately versus online that takes many seconds

Hi, any progress on this issue

Hi @benjamin-almarza, thanks for asking. We don't have a plan to fix this issue in the short term. However, can you let me know what is your use case here?

[benjamin-almarza]

Our application is managing large number of documents on behalf of our customers, those documents are usually extracted (downloaded for edit) from our system and redlined, changed or formatted in MS Word. Our customers use both Office 365 as well as desktop MS Word in order to manage the documents. Right now we rely on the frequent content snippets insertion. The delay in inserting "OOXML" in the web is far too significant, it is causing a very poor user experience and basically is not useable. Therefore we are forced to go for workaround and user "HTML" instead. That introduces another host of issues for us because "HTML" doesn't preserve the style as well as "OOXML", and therefore we have an inconsistent behaviour and inconsistent user experience. The request is to address the issue with "OOXML" insert in the web application (Office 365), so that system providers like us could find Microsoft web application reliable and compatible and so that end users would receive best experience possible.

For content snippets, do you mean content controls? Or other types of content that you want to insert into the document?
