Sometimes we need to update only a single column of a record(s), although this can be done through the user interface, sometimes it can be tricky when other columns are compulsory or you have a lot of records to update/do it regularly. The update in bulk via excel online can be used, but you will need to create a view with only the columns you want to change and it takes a while to process them.
With this Power Automate flow, once you create it, you can change it for future update records, and you can also use it to update multiple records with some changes. If you are updating larger numbers of records you want the batch/bulk update Web API requests though.
