Removing Certain Words In A Cell

removing certain words/charactors in a cell.

For example, I have these information in 1 excel cell.

"Company allows staff to purchase small value items (items amounting to less than $3000) with approval from the staff's director."

So in this case, I need to remove the HTML/XML tags manually. Therefore, the final result should be,

"Company allows staff to purchase small value items (items amounting to less than $3000) with approval from the staff's director."

It is very tedious with the huge amount of data to process.
