Difference between used range and current region in VBA.

In VBA, both UsedRange and CurrentRegion are methods used to determine the data range, but they have some differences.

1. The range of cells that have been used.
2. UsedRange is a property that determines the area of a worksheet that has been used. It returns a range object representing all the used cells, including empty cells. In other words, UsedRange extends to the maximum range on the worksheet, regardless of data presence.
3. You can use the UsedRange property in the following way:
   Dim rng As Range
   Set rng = ActiveSheet.UsedRange
4. Care should be taken when dealing with UsedRange as it may expand to the maximum range of the worksheet and include some unnecessary blank cells.
5. The region in which we are currently located.
6. The CurrentRegion method is used to identify the contiguous range of a given cell area. It returns a range object representing the continuous range of cells surrounding the specified cell, excluding any blank cells. In other words, CurrentRegion only includes non-empty cells surrounding the specified cell.
7. The CurrentRegion method can be used as follows:
   Dim rng As Range
   Set rng = Range(“A1”).CurrentRegion
8. The CurrentRegion method requires a specified starting cell, and then it will automatically expand to include a range of consecutive non-empty cells.

In summary, both UsedRange and CurrentRegion are methods used to determine data ranges, but UsedRange includes the maximum range of the entire worksheet, while CurrentRegion only includes non-empty cells around the specified cell. Depending on specific needs, choose which method to use.
