7 Ways to Ignore Errors in Excel Entire Sheets

Excel, Microsoft's premier spreadsheet software, is renowned for its powerful features that cater to data analysis, financial modeling, and various other tasks involving numbers and data manipulation. However, even the most adept users can encounter errors, which can range from simple typos to complex formula issues. Here's a detailed guide on 7 different ways to handle and ignore errors in entire sheets within Excel, ensuring your data presentations remain clean, professional, and error-free.

1. Using Conditional Formatting to Hide Errors

Conditional Formatting in Excel can be used to visually hide errors without actually deleting them. This technique changes the appearance of cells based on criteria:

• Select your range or entire sheet.
• Go to Home tab, click Conditional Formatting, then New Rule.
• Choose Use a formula to determine which cells to format.
• Enter the formula: =ISERROR(A1) (replace A1 with the first cell of your selection).
• Click Format, choose a fill color that matches your sheet’s background.

This method will color cells with errors to blend into the sheet’s background, effectively hiding them visually.

❗ Note: This method only hides the errors; they still exist in the cell’s value.

2. IFERROR Function

The IFERROR function is perhaps the most straightforward way to deal with errors in Excel. Here’s how to use it:

• Enter the formula into your cell: =IFERROR(AVERAGE(A1:A10), 0)
• IFERROR will replace any error resulting from the AVERAGE function with the specified value (0 in this case).

This function can be used for any formula where you anticipate potential errors.

3. AGGREGATE Function

The AGGREGATE function offers a robust method to ignore errors in array operations:

• Use AGGREGATE with options 6 or 7 to ignore errors. For example, to calculate the average while ignoring errors:
• =AGGREGATE(1, 6, A1:A10)

This function provides a way to perform calculations on a range of cells while ignoring any errors within that range.

4. Custom VBA to Skip Errors

For advanced users, Visual Basic for Applications (VBA) can automate the process of ignoring errors:

• Open the VBA editor with Alt + F11, insert a new module, and write code like:

Function IgnoreErrors(rng As Range) As Double
    Dim cell As Range
    Dim total As Double
    Dim count As Integer

For Each cell In rng
    If Not IsError(cell.Value) Then
        total = total + cell.Value
        count = count + 1
    End If
Next cell

If count = 0 Then
    IgnoreErrors = 0
Else
    IgnoreErrors = total / count
End If


End Function

• Call this function in your Excel sheet as: =IgnoreErrors(A1:A10)

This custom function will calculate the average of non-error cells in a specified range.

5. Using FILTERXML to Ignore Errors

Although not common, FILTERXML can be used in Excel 365 and later versions to filter out errors:

• Enter: =AVERAGE(FILTERXML(”” & SUBSTITUTE(TEXTJOIN(“|”, TRUE, A1:A10), “#”, “”) & “”, “//r[not(starts-with(.,‘#’))]”))

This complex formula essentially filters out any text containing ‘#’ (which signifies errors in Excel).

6. Error Suppression with ISERROR and IF

Combining ISERROR with IF gives a basic but effective way to manage errors:

• =IF(ISERROR(AVERAGE(A1:A10)), 0, AVERAGE(A1:A10))

If the AVERAGE function results in an error, it’ll display 0, otherwise the average value.

7. Error Handling with CHOOSE and MATCH

This method involves using CHOOSE and MATCH functions together to handle errors:

• Construct a formula like: =CHOOSE(MATCH(TRUE, ISERROR(A1:A10), 0), A1, A2, …, A10)

This will return the first non-error value from the range A1:A10.

The above methods provide multiple avenues for dealing with errors in Excel sheets, each with its own application. By understanding and applying these techniques, you can significantly enhance your Excel workflow, ensuring that errors do not impede your productivity or the professional presentation of your work. Remember, while it's crucial to manage errors, equally important is to understand why they occur to prevent them in the future. This balance between error handling and data integrity will lead to a more efficient use of Excel.

Why should I ignore errors in Excel?

+

Ignoring errors in Excel can clean up your data presentation, allowing you to focus on accurate data analysis without being distracted by errors. It’s also useful when errors are not critical or when the formulas are set to run calculations over large datasets where some errors might occur.

Is it safe to ignore errors in Excel?

+

Ignoring errors can be safe if you understand the data and context. However, always ensure you’re not hiding critical errors that could lead to misinformation or incorrect decisions. Use these techniques judiciously.

Can I revert the ignoring of errors if I need to?

+

Yes, if you’ve used conditional formatting or functions like IFERROR, you can easily revert or modify the settings to show errors again. For VBA solutions, you might need to change or remove the custom function.

What are some common errors I might encounter in Excel?

+

Common errors include #DIV/0! (division by zero), #N/A (not available), #VALUE! (incorrect type or argument in formula), #NAME? (formula contains unrecognized text), and others.

How can I prevent errors in Excel?

+

Regularly validate your data, use Data Validation to restrict input, check your formulas for logical errors, and utilize Excel’s error checking features to identify and correct issues before they become problematic.
