Small Script Modification

Hello! I have a very small script that is a executable file, basically when executed it feeds an excel table (when executed for the first time it creates this table) with some values given in the installation and with time and date, saves a screenshot in a folder in the computer specified in the installation, then uploads that same screenshot to a ftp address given at the installation and then opens a url also given at the installation. The things i need to modify are the following: - I need this instead of using Microsoft Excel for creating a table and then feeding it, to use libreoffice excel to do the same function, but saving the file in microsoft excel format. - At the installation a option to specify the ammount of stand by seconds before another activation of the executable is allowed. - Option to have a specified ammount of screenshots uploaded to the ftp folder before it re-writes the first one and continue like that. (this software have that option but i doesnt work it need to be corrected or modified) - Captures must be custom named. (Select the screenshots name in the installation, for example if i select the name "screenshot-motorcycle" the screenshots will be "screenshot-motorcycle-1" "screenshot-motorcycle-2" etc) - Some fields that now are required to be written in the installation (for example some names that will feed the excel table) must be pre defined in the software and hidden fron the installation form. - 5 excecutables must be delivered with 5 different hidden pre defined fields that i will provide when needed. - Full source code must be delivered. That are all the changes, i have the full source code for what is developed till now and described above. Regards!
