noProof Attribute Applied to Merge Fields during Mail Merge to Turn Off Proofing in a Word 2016 RTF (NoProofing) Java Code

I’m having an issue with Aspose Word turning off Proofing functionality after I use its Mail Merge feature, for the values that are inserted into the document. Aspose was never asked to turn proofing off and the initial document has it turned on by default.

Looping through the document to turn proofing back on does not appear to fix the problem in the final document. After I’m done, it still comes out with proofing off. In fact, by looping through the whole document and setting setNoProofing() to any value, whether true or false, it will turn off proofing for every part of the document. Whereas, if I don’t loop and set that value, only the merge field will have proofing turned off. Either way it is a no win situation for our customers.

We have performed manual mail merge on your ‘input.rtf’ by using MS Word 2019 and observed that the behavior of MS Word 2019 is same as that of Aspose.Words’. Please check the following MS Word 2019 generated RTF file:

So, this does not seem to be a bug in Aspose.Words for Java API. Aspose.Words applies noProof attribute for mergefield field result during mail merge like MS Word does.

Secondly, we managed to reproduce this issue on our end when running the following simple code:

Document doc = new Document("E:\\Temp\\ProofingSample\\input.rtf");

for (Run run : (Iterable<Run>) doc.getChildNodes(NodeType.RUN, true)) {
    run.getFont().setNoProofing(false); // any value true/false will turn off proofing
