Hi Roni,

To convert 15-minute data to hourly, you can use the
Formula:
``` AVERAGEIFS  ```
function in Excel. Here are the steps:
1. Insert a new column next to column A and label it "Hourly".
2. In the first cell of the Hourly column (B2), enter the following formula:
Formula:
``` =AVERAGEIFS(B:B,A:A,"="&A2,A:A,"<"&A2+TIME(1,0,0))  ```
3. Press Enter and the average value of the data for the first hour (18:00-18:59) will be displayed in cell B2.
4. Copy the formula in cell B2 and paste it down to the rest of the cells in the Hourly column.

The
Formula:
``` AVERAGEIFS  ```
function calculates the average of the data in column B that meets the criteria specified in the function. In this case, we want to calculate the average for each hour, so we use the criteria "="&A2 and "<"&A2+TIME(1,0,0), which means the date and time in column A must be greater than or equal to the current hour (A2) and less than the next hour (A2+TIME(1,0,0)).
