I have received a spreadsheet which has the dates formatted with only numbers without separators and I would like to transform them into a date format. For example, I would like to change the number 20201130 to 2020/11/30. How could I do it?

Please use the following


(adjust the range to your needs and format as date)

How the formula works:
Because REGEXREPLACE takes only text values we use TEXT to turn the numbers to text, edit them and then turn them again to numbers using ^1.
We also use the IF function to get rid of blank cells and ArrayFormula to do the whole column in one go.
