If you only have one group, use a two way ANOVA in Excel without replication.

Can I use one-way ANOVA?

With a balanced design, you can safely use a one-way anova unless the sample sizes per group are less than 10 and the standard deviations vary by threefold or more. If you have a balanced design with small sample sizes and very large variation in the standard deviations, you should use Welch’s anova instead.
