How to utilize date add function in Google spreadsheet?

Question

I believe the issue I am having now should be much easier in MS Excel. However, since my company uses Google Spreadsheet so I have to figure out a way.

Answer 1

1. To extract a numeric value out of your string you can use these 2 functions (Assuming you have your value in cell 'A1'):

   =VALUE(REGEXEXTRACT(A1, "\d+"))

   This will get you a numeric value.

2. I've found no date add function in docs, but you can convert your date into internal date number and then add days number (If your value is in cell 'A2'):

   =DATEVALUE(A2) + 30

I hope this will help.
