how to find the location of a specific element in a matrix or in a excel file

i need to find the location of each element from the matrix/excel, how can i do it through matlab functions? if not possible with functions than how ca I do this with loop? please provide me a sample code to do so. Actually I think functions would work great for large data processing, loops will take more time. Attaching a sample file

Stage	health	Object
1	good	chair
2	good	table
3	bad	fan
4	average	bag
5	average	laptop

identify position , functions , location finding , loops

What do you mean "to find the location of each element"? You mean just read the file, don't you; the location is really of very little significance for a regular file structure such as that file contains.

fn='example.xlsx';
tData=readtable(fn);
tData=convertvars(tData,@iscellstr,'categorical')

tData = 5×3 table
    Stage    health     Object
    _____    _______    ______

      1      good       chair 
      2      good       table 
      3      bad        fan   
      4      average    bag   
      5      average    laptop
