Find/Replace within Custom Property Value

Hi Guys,

I've got a case where I have hundreds of files which have an incorrect string of numbers within a custom property value.

The custom property value of these files includes the string of numbers and a bunch of other text. I require just the string of numbers to be changed - but the text to remain.

Ideally I would like to process the hundreds of files in a batch also.

I am aware of an application called PropaGator which can do this using a find and replace function.

How ever unfortunately this application no longer works with Solidworks versions 2015 and 2016.

Does anybody know of anything out there that can do this?

Could a macro do this? I have no macro experience.
