Yes, Excel can be used to calculate the geometric standard deviation (GSD) of a dataset. Here are the steps to do so:

First, calculate the geometric mean of the dataset using the

Formula:

GEOMEAN

function in Excel. For example, if your dataset is in cells A1:A10, you can use the formula =GEOMEAN(A1:A10) to calculate the geometric mean.
Next, calculate the logarithm of each data point in the dataset using the

Formula:

LN

function in Excel. For example, if your dataset is in cells A1:A10, you can use the formula =LN(A1:A10) to calculate the logarithm of each data point.
Calculate the average of the logarithms using the

Formula:

AVERAGE

function in Excel. For example, if you calculated the logarithms in step 2 in cells B1:B10, you can use the formula =AVERAGE(B1:B10) to calculate the average of the logarithms.
Calculate the variance of the logarithms using the

Formula:

VAR.P

function in Excel. For example, if you calculated the logarithms in step 2 in cells B1:B10, you can use the formula =VAR.P(B1:B10) to calculate the variance of the logarithms.
Calculate the square root of the variance from step 4 to get the standard deviation of the logarithms.
Finally, calculate the exponential of the standard deviation from step 5 to get the GSD. You can use the

Formula:

EXP

function in Excel to do this. For example, if you calculated the standard deviation in step 5 in cell C1, you can use the formula =EXP(C1) to calculate the GSD.

That's it! You have now calculated the GSD of your dataset using Excel.
