Hi I have some dates across multiple columns and i need to filter out those that don't match dd/mm/yyyy and also filter out empty values.
I also have some values across multiple columns that should show numbers but the data is dirty and also showing weird characters, words and letters which also need to be filtered out, as well as show empty values.
Because the both above are across multiple columns (all string columns), whats the most efficient way to filter out? Would be helpful to be provided some guidance on this or a workflow i can add into mine.
