First post here, so sorry about formatting/missing details. I have a data set that is just a numeric ID and a month value that is a string in format YYYY-M (e.g. September 2017 would be 2017-9). All of the values are in 2017 or 2018. I need to create a row for each ID for each month from the value provided up to December 2018. I also have these dates in a raw date format as well if that would make this easier. So for example, the input 5134223 2018-10 Would need to output 5134223 2018-10 5134223 2018-11 5134223 2018-12 ^having trouble with the formatting here but these should be on 3 separate lines. If anyone can provide any help that would be amazing. Again, I can get these dates in a normal date format but the way I have been approaching it was going to use it as a string until I got stuck.
