I have two database dumps in Google sheets. They contain several thousand entries - many are identical, but not all. I now need to find all of those where a number in a specific column has increased by a certain number. The problem is that the rows not necessarily are the same, as entries in the database can have been deleted - and more been added, so rows do not add up.
I have tried various forms of 'if' and 'query' - none that have brought me closer to a solution.
I'm thinking that I first need to compare the column where the unique id is to ensure that it is the right entry that is being compared.
I would like to completely automate this, but a semi-manual way of doing this could also be okay.
One solution for this could be to get Google to check the unique id's of the two tabs - and then display the content of a second column in the first tab only where the id's can be found in both tabs. I just cannot get Sheets to do this.
Any help would be appreciated
