Check out the white paper on calculating CAPM beta using the regression functions in NumXL
https://numxl.com/blogs/calculating-capm-beta/
To estimate the CAPM beta, you need to regress (SLR) between the two-time series: market returns and your asset returns.
Asset Return = risk-free return + beta * Market Return
You can use the NxRegress function to compute the slope (i.e. Beta) for the two-time series. See the function reference page and example:

You can even compute the beta value for different dates (using prior data) and examine the variation of beta over time.
