Extract date and specific string from text

You just need to use the Extract menu under the Add Columns tab, making sure you choose Text  store or Text After Delimiters, making sure the parameters include whether to start from the beginning or end of the string.

You can extract the components using Regular Expressions. You can implement Regular Expressions using a Custom Function or, if you are running Power Query in Power BI, you can also use Python or R.
