Change Value in U iMACROS with the firefox


i am using U iMACROS with the firefox extension

i have completed a script that works well

i have many values to change in the script to be able to perform the same operation on other documents

i would like to know how i can change automatically the value without having to do it manually

For example: with a EXCEL sheet or another plugin ???

Thank you so much for your help
