Excel value to web applicaiton input box has characters missing randomly

I have an excel file which has many rows of the search text. My code works fine most of the times but randomly it is missing characters when it is trying to enter values in the textbox. Due to this, I have to watch the program running and manually correct the values for my script to run and go to further steps.

Is this problem of text box typing are reading the issue from excel? And what can be done to solve this?
