If you want to group time by minutes intervals, also can use formulas.

I have the duration of the data (not time stamp) in each cell. I want to be able to be able to group into less than 5 minute, 5-10 minutes, 10-15 minutes, 15+. How would I do that. Note: the time durations are displayed HH:MM:SS

Thanks

Hi, Nicolas C Petraglia, try formula =FLOOR(A2,TIME(0,5,0)), and drag auto fill handle down to all cells you want to group. See the screenshot shown:

Hi, I need to figure out how to align a column of data with one-hour timestamps to a column of data with 5-minute timestamps.  I don't want to average the 5-minute data at all, nor do I want to round the timestamp using FLOOR, I just want to distribute the one-hour data points down the column beside the 5-minute data so they line up.
i.e. the one-hour data column must have 11 blank rows so that it aligns with the same ":00" timestamp in the 5-minute row.  How can I do this?

Hi, Guest, I do not understand your problem. My understanding is that insert blank 11 rows to make one-hour timestamps align with 5-minutes timestamps. If so, copy and past the 5-minutes timestamps to the other sheet firstly, then select the one-hour timestamps selection and apply Kutools for Excel's Insert Blank Rows feature and set insert 11 rows per row, and then copy and paste the 5-minutes timestamps back. For more detail for Insert Blank Rows, please visit:https://www.extendoffice.com/product/kutools-for-excel/excel-insert-blank-rows-column.html
