put string to cell keyword not working

[GoogleCodeExporter]

i have an excel sheet and i am trying to write string to a cell using put 
string to cell keyword but it is not reflecting in excel sheet. the cell which 
i am writing to has value 0.


What is the expected output? What do you see instead?
the expected output is string should be written in excel but it is not writing 
to cell and not throwing any error also.

What version of the product are you using? On what operating system?
Robot frame work 2.8.5 on python 2.6 with operating system as linux

Please provide any additional information below.
first i tried to write to an empty cell but it returned list index out of range 
error. so i filled that cell with 0 then am using put string to cell to write 
to that cell.
