Adding A "Clear" Button to Worksheet to Clear a Range of Data

Hi all,

Looking for some help with how to create a button on an excel file to clear a range of data (but not the whole worksheet) for easier clearance of data, rather than having to do it manually.

I have attached the worksheet for reference and below is the ranges that i want to clear using the macro button:

298R x 20C (A3:T3 and down 300 rows) and 298R x 4C (W3:Z3 and down 300 rows.

This leaves formatting and column headers as well as some formula in the middle of the document without clearing.

Any help will be greatly appreciated!

Thanks
