I’ve got this project which loads an HTML page and pulls info from a Google Sheet and displays it on the webpage. The code works fine, but it takes a while to pull from the input field, run the necessary functions and return a response. Are there some things I could be doing to improve the speed?

I have created a web app using Google Apps Script and JavaScript to search through the data on a spreadsheet. Rows 0, 2, 3, 4, and 5 all have a combination of numbers and letters and return results without issue. Row 1 has only numbers, and if I uncomment it, I get no search results at all from any rows. I suspect I am missing something easy and obvious, but being very new to this, I have hit a brick wall. I am keen to overcome it. I am searching for input type text, if I change this to number row 1 still returns no results. Any advice or support would be appreciated.
