Hi @Jayshiv1408Dev Thanks for reaching us. Could you please give us more detail info for your scenario about what you want to do or your issue? such as you want to use office API JS to set character 'st' as superscript/subscript/strike? May I know you want to implement on Word Online or Word desktop? Thanks.

Hi @shanshanzheng-dev, Thanks for your quick response.
Sorry for inconvenience I forget to add details.

My Environment
Platform : PC desktop
Host: Word
Office version number: Microsoft® Word for Microsoft 365 MSO (Version 2404 Build 16.0.17531.20140) 64-bit
Operating System: Microsoft Windows 11 pro

I'm taking value from excel and putting that into my word table.
In that some cell has superscript or subscript on some character so I want to give that style to particular character only.

word table cell has this text **21st Jan 2022**
supText="st"; 
 const searchResults = cell.body.search(supText, { ignoreSpace: true });
 context.load(searchResults);
 await context.sync();
 searchResults.items[0].font.superscript = true;

It's working fine until this kind of value is come

As given Image you can see 21st and 22nd January.
For this text when I used Below code Its giving me this kind of output.
I know I used 0 index that's why its happening.
Is there way I can Search text based on index Or I can get range base on start-index and length/endIndex

hi @Jayshiv1408Dev thanks for reaching out. After inspecting the questions mentioned above, I am afraid so far there is no existing API to get range based on start-index and length/endIndex. This will be a new feature ask, we track Office Add-in feature requests on our Microsoft 365 Developer Platform Ideas Forum. Please add your request there. Feature requests on are considered when we go through our planning process. Thanks,

@jipyua Thanks,
Is there other way I can achieve this.

[jipyua]

hi @Jayshiv1408Dev I am afraid so far there is no directly available APIs for your request, there is a split API here https://learn.microsoft.com/en-us/javascript/api/word/word.range?view=word-js-preview#word-word-range-split-member(1) for spliting ranges, but please validate whether you can find suitable delimiters for your purposes. Thanks.

Thanks @jipyua and @shanshanzheng-dev for your help.
I'll check this api.
