In Excel, you can use the ROUNDUP and ROUNDDOWN formulas to round the numbers up or down.

Select a cell next to the data, and type this formula =ROUNDUP(A2,1) (A2 is the data cell you need to round up), and drag the fill handle to the cells you need. See screenshots:

Tip:

In above formulas, 1 indicates keeping one decimal, you can change it as you need, and if you want to round number up or down to whole number, you can use formulas =ROUNDUP(A2,0) or =ROUNDDOWN(A2,0).
