How to make custom Word-Addin check for misspellings using Office-js API

Question

I want to create a word-addin that will show error (underline the misspelled words in red curvy line) for misspelled words. Also, like in word when you misspelled a word it shows red line and when you right click it, it gives some suggestions for correct words. I am trying to make that for Bangla language using Office-js. I have not found any tutorial regarding this.

I have seen the office documentations. There is an API for enabling dictionary in word: https://docs.microsoft.com/en-us/office/dev/add-ins/word/dictionary-task-pane-add-ins . I am hoping to find a similar thing but for checking misspelling words. Also if there is option for context based misspelling then it will be better.

Answer 1

You can create custom dictionaries for Word: How to add a custom dictionary in Word. This would make use of the existing, very fast, real-time, Word spell checker. If making spell check possible for writers of Bangla is your goal, then I think this is what you should do.

If you must have an add-in rather than a dictionary, please respond and we can think of how you might implement one with an add-in.
