Sorting data by time.

Take this:

 

Question 1: Filtering Data by Time
To filter data in Excel based on time intervals (e.g., removing rows with less than 5 minutes between each other), you can use a combination of formulas and sorting. Here's a step-by-step approach:

• Add a Helper Column: Insert a new column next to your time column (let's say Column A has your time data). In the helper column (Column B), calculate the time difference between each row and the previous row. You can use the formula:

=IF(A2=A1, TEXT(0, "mm:ss"), TEXT(A2-A1, "mm:ss"))

• Sort by Helper Column: Sort your data by the helper column to group rows with less than 5 minutes difference.
• Filter Rows: Use the filter function to remove rows where the helper column shows less than 5 minutes.

 

Question 2: Compressing Duplicated Coordinates
To compress duplicated coordinates in Columns E and F without losing data from other columns, you can use a combination of formulas and conditional formatting:

• Identify Duplicates: Use a formula to identify duplicates in Columns E and F. For example, in Column G, you can use:

=IF(COUNTIF(E:E, E2)>1, "Duplicate", "Unique")

• Conditional Formatting: Apply conditional formatting to highlight duplicates in Columns E and F.
• Remove Duplicates: Manually delete the highlighted duplicates or use a more advanced formula to compress them while keeping data from other columns intact.
