let
Source = Excel.CurrentWorkbook(){[Name="SalesData"]}[Content],
RemoveDuplicates = Table.Distinct(Source),
ChangedType = Table.TransformColumnTypes(RemoveDuplicates,{{"Date", type date}, {"Amount", Currency.Type}})
in
ChangedType
What This Code Does:
This Power Query M code snippet loads the 'SalesData' table, removes duplicate entries, and ensures the 'Date' and 'Amount' columns are correctly typed.
Business Impact:
By automating data cleansing, businesses can reduce errors associated with manual data entry, leading to more reliable reports and analyses.
Implementation Steps:
1. Open Power Query Editor in Excel. 2. Load your dataset into Power Query. 3. Use the provided M code to automate data cleansing.
Expected Result:
A clean, de-duplicated dataset ready for analysis
3. Implement Rigorous Data Validation and Conditional Formatting
Robust data validation rules are crucial for ensuring data accuracy. Use Excel’s data validation tools to restrict inputs to certain types, such as numbers or dates, thus minimizing errors at the point of entry. Conditional formatting can highlight anomalies, enabling quick visual checks for accuracy.
Sub ApplyDataValidation()
Dim ws As Worksheet
Set ws = ThisWorkbook.Sheets("Sheet1")
With ws.Range("A1:A100").Validation
.Delete
.Add Type:=xlValidateWholeNumber, _
AlertStyle:=xlValidAlertStop, _
Operator:=xlBetween, _
Formula1:="1", Formula2:="100"
.IgnoreBlank = True
.InCellDropdown = True
.InputTitle = "Enter a number"
.ErrorTitle = "Invalid entry"
.InputMessage = "Please enter a number between 1 and 100."
.ErrorMessage = "Only numbers between 1 and 100 are allowed."
End With
End Sub
What This Code Does:
This VBA macro applies data validation to the range A1:A100, ensuring only whole numbers between 1 and 100 are entered, thereby preventing invalid data entries.
Business Impact:
By enforcing data validation, businesses can significantly reduce erroneous data entries, leading to more reliable analyses and reports.
Implementation Steps:
1. Press Alt + F11 to open the VBA editor. 2. Insert a new module. 3. Copy the provided macro and run it to apply data validation.
