Description: After replacing e.g. 31122020 with 31.12.2020 using the search and replace function, the cells are formatted as dates. When undoing the replacement the number-format stays, writing all 7 or 8-digit numbers as dd.mm.yyyy. Steps to Reproduce: 1. Replace "([0-9]{1,2})([0-9]{2})([0-9]{4})" by "$1.$2.$3" using regular expressions (german date format) 2. Undo replacement Actual Results: Previous cell value interpreted as date Expected Results: Previous cell value shown with the previous format Reproducible: Always User Profile Reset: No Additional Info: Automatic date detection is enabled and set to german date format.
Reproducible, the behavior, it's not the same as working directly on the cells.
