I have a script that I am going to implement to some 100 is sheets. The script is needed to copy over new rows from all sheets into a centralized sheet. We are currently using import range but it seems to break all the time due to the volume of sheets that are being imported from.
My question is: Is there a way to "Copy" over my script to the 100 sheets without having to manually go one by one and Tools > Script Editor > Paste > Save > Close and repeat ?
