Please reply with a few sample album names. Include a few with the date spec in any position you think it can occur. Do not leave out the non date text in the examples.

'1999.02.10 covert to 1999-02-10' makes no sense. I'm assuming you have DD-MM-YYYY or MM-DD-YYYY and you want YYYY-MM-DD.

Also need to know which of DD-MM-YYYY or MM-DD-YYYY is currently used. It is not always possible to tell by looking at the text.

ie. is 02.10.1999 Feb 10, 1999 or October 2, 1999?

You say period and slash but your example has underscores and dashes 🙂

I can handle both periods and underscores. Do you still want it moved to the front?

example:

does

Roseland Theater Portland 2005.10.13

become

2005.10.13 Roseland Theater Portland

Still not clear if I have to worry about MM.DD.YY? ie. can I see the following: 10.13.2005 Roseland Theater Portland

Download the action at: https://2manyrobots.com/actions/CorrectDatesInAlbum.zip

This will give you an action named Correct Dates in Album

It will handle periods (.) slashes (/) underscores (_) and dashes (-) as delimiters.

Using any of the four supported delimiters, it will handle dates entered as YYYY MM DD or MM DD YYYY

If found the date will be removed and rewritten as YYYY-MM-DD at the start of the field.

The action has a side effect of removing all leading and trailing spaces and compressing all sequences of multiple spaces into a single space.

The action will run in immediate mode or in the Batch Processor. Note that the action does not save changes. If you run it through the Batch Processor make sure to enable the Auto-Save option when the options are displayed.
