=ERROR.TYPE(error_val)

Quick Answer

TL;DR

ERROR.TYPE function ERROR.TYPE function returns a number (1-7) identifying Excel's seven standard error types like #N/A, #VALUE!, or #DIV/0!. Use syntax `=ERROR.TYPE(error_val)` where error_val is a cell reference or formula that may contain an error. Combine with CHOOSE to create custom error messages instead of displaying cryptic error codes.

=ERROR.TYPE(error_val)

Comprehensive Explanation

## What is ERROR.TYPE?

ERROR.TYPE is Excel's built-in error diagnostic tool and part of the Information functions family. It returns numeric codes for seven standard error types, making it essential for advanced error-handling strategies. Available in all Excel versions (Excel 2003+) and Google Sheets, ERROR.TYPE provides specific error identification unlike ISERROR, which only returns TRUE/FALSE.

## Understanding Error Number Mapping

ERROR.TYPE returns specific codes for each error type:

**1 = #NULL!** - Range intersection error (missing range operator)

**2 = #DIV/0!** - Division by zero error

**3 = #VALUE!** - Wrong value type in formula

**4 = #REF!** - Invalid cell reference (deleted cells)

**5 = #NAME?** - Unrecognized function or range name

**6 = #NUM!** - Invalid numeric value

**7 = #N/A** - Value not available (common with VLOOKUP)

**#N/A (returned)** - No error detected in the input value

Importantly, when ERROR.TYPE evaluates a valid value (not an error), it returns #N/A to indicate "no error detected." This behavior is often unexpected but is by design.

## Core Functionality

ERROR.TYPE operates through a straightforward process:

1. **Receives Input:** Accepts a cell reference or formula as input
2. **Evaluates Error State:** Checks if the value is an error
3. **Identifies Error Type:** Determines which of the 7 error types it matches
4. **Returns Code:** Returns corresponding number (1-7) or #N/A if no error

The function can be nested within other functions for conditional logic and works with both direct error references and formulas that produce errors. This makes it extremely versatile for building sophisticated error-handling systems.

## When to Use ERROR.TYPE

**Custom Error Messages:** When you need to display user-friendly messages instead of #N/A or #VALUE!, ERROR.TYPE combined with CHOOSE or SWITCH creates readable error descriptions that help users understand what went wrong.

**Error Logging:** Building audit trails that track specific error types allows you to identify patterns in data quality issues. For example, frequent #N/A errors might indicate missing reference data, while #REF! errors suggest structural problems.

**Conditional Formatting:** Applying different formats based on error type helps visually distinguish between critical errors (#REF!, #NAME?) and data errors (#N/A, #DIV/0!).

**Data Validation:** Identifying why imported data failed validation enables targeted data cleaning. Different error types require different correction strategies.

**Advanced Error Handling:** Creating intelligent fallback logic that responds differently to different errors. For instance, retry lookups for #N/A errors but alert users immediately for #REF! errors.

## Key Advantages Over Alternatives

**vs ISERROR:**
ERROR.TYPE provides specific error identification, while ISERROR only returns TRUE/FALSE. This specificity enables targeted error handling for different error scenarios, making it more powerful for complex error-handling logic.

**vs IFERROR:**
IFERROR masks errors and shows alternatives, while ERROR.TYPE identifies them. Use ERROR.TYPE when you need to know WHICH error occurred, not just suppress it. IFERROR is simpler for basic error suppression, but ERROR.TYPE excels at error diagnosis.

**vs Multiple IS Functions:**
A single ERROR.TYPE call replaces ISNA, ISERR, and other specific error-checking functions. This is more efficient than chaining multiple error-checking functions and provides cleaner formula syntax.

## Platform Compatibility

**Excel 365/2021:** Full support with dynamic arrays, allowing array-based error analysis

**Excel 2019/2016:** Standard implementation with all core features

**Excel 2013/2010:** Full support with identical behavior

**Excel 2007/2003:** Supported since original implementation

**Google Sheets:** Full compatibility with identical syntax and return values

**Excel Online:** Complete support across all features

ERROR.TYPE is one of the few functions with zero compatibility issues across platforms, making it reliable for cross-platform spreadsheets and templates shared between Excel and Google Sheets users.

Practical Examples

Common Errors and Solutions

#N/A

ERROR.TYPE returns #N/A instead of expected number

Cause:

ERROR.TYPE returns #N/A when the input value is NOT an error. This is the function's way of indicating "no error detected." Many users expect a number or text message, but #N/A is the correct response for non-error values.

Solution:

Wrap ERROR.TYPE in IFERROR or IF(ISERROR(...)) to handle valid values: ```excel // Instead of this: =ERROR.TYPE(A1) // Returns #N/A if A1 = 100 // Use this: =IFERROR(ERROR.TYPE(A1), "No error") // Or this: =IF(ISERROR(A1), ERROR.TYPE(A1), "Valid value") ``` **Best Practice:** ```excel =IF(ISERROR(A1), "Error type " & ERROR.TYPE(A1), "Value is valid: " & A1) ```

Prevention:

Always expect #N/A as a possible result. Design your error-handling logic to account for both error states (1-7) and non-error states (#N/A). Use ISERROR as a pre-check before applying ERROR.TYPE.

Frequency: 55%

Example:

#VALUE!

Formula returns #VALUE! error

Cause:

ERROR.TYPE returns #VALUE! when you pass a direct value instead of a reference to an error. For example, =ERROR.TYPE("text") returns #VALUE! because "text" is not an error value, and ERROR.TYPE expects either an error value or a formula that might produce one.

Solution:

Use cell references or formulas that can produce errors: ```excel // Wrong: =ERROR.TYPE(100) // Returns #N/A (valid value) =ERROR.TYPE("text") // Returns #VALUE! // Correct: =ERROR.TYPE(A1) // Where A1 contains #N/A =ERROR.TYPE(10/0) // Produces #DIV/0!, returns 2 =ERROR.TYPE(VLOOKUP("X",B:C,2,0)) // May produce #N/A ``` **Quick Fix:** ```excel // Test all error types =ERROR.TYPE(NA()) // Returns 7 (#N/A) =ERROR.TYPE(1/0) // Returns 2 (#DIV/0!) ```

Prevention:

Always reference cells or formulas, not static values. If testing, use formulas that generate errors: =ERROR.TYPE(1/0) for #DIV/0!, =ERROR.TYPE(NA()) for #N/A.

Frequency: 25%

Example:

Logic Error

Custom messages display incorrectly

Cause:

Mismatching error codes with CHOOSE function positions. CHOOSE is 1-indexed, and ERROR.TYPE returns 1-7, so the arrays must align perfectly. Common mistake: forgetting that CHOOSE's first argument is the index, leading to off-by-one errors.

Solution:

Verify your CHOOSE array matches ERROR.TYPE codes exactly: ```excel // Wrong - misaligned messages =CHOOSE(ERROR.TYPE(A1), "Division by zero", // Position 1, but should be NULL "Null error", // Position 2, but should be DIV/0 ...) // Correct - properly aligned =CHOOSE(ERROR.TYPE(A1), "NULL intersection", // 1 = #NULL! "Division by zero", // 2 = #DIV/0! "Invalid value", // 3 = #VALUE! "Invalid reference", // 4 = #REF! "Unknown name", // 5 = #NAME? "Invalid number", // 6 = #NUM! "Value not available") // 7 = #N/A ``` **Reference Table:** | Code | Error | Message Template | |------|-------|------------------| | 1 | #NULL! | "Range intersection error" | | 2 | #DIV/0! | "Division by zero" | | 3 | #VALUE! | "Invalid value type" | | 4 | #REF! | "Invalid cell reference" | | 5 | #NAME? | "Unrecognized name" | | 6 | #NUM! | "Invalid numeric value" | | 7 | #N/A | "Value not available" |

Prevention:

Create a reference table mapping error codes to messages. Test each error type individually to verify correct message display.

Best Practices and Advanced Tips

Combine with INDIRECT for Dynamic Error Analysis

Use ERROR.TYPE with INDIRECT to analyze errors across multiple sheets dynamically. For example, =ERROR.TYPE(INDIRECT("Sheet" & A1 & "!B2")) checks specific cells across different sheets based on a sheet number in A1. This technique is invaluable for error monitoring in multi-sheet workbooks or consolidated reports.

Create Error Type Constants for Readability

Define named ranges for error codes to make formulas self-documenting. Create names like ERROR_NA=7, ERROR_DIV0=2, etc. Then use IF(ERROR.TYPE(A1)=ERROR_NA, ...) instead of remembering numeric codes. This dramatically improves formula readability and maintenance, especially in complex workbooks shared across teams.

Build Error-Resilient Array Formulas

In Excel 365, combine ERROR.TYPE with FILTER to create arrays that exclude certain error types while preserving others. For example, =FILTER(A:A, ERROR.TYPE(A:A)<>7) removes #N/A errors but keeps other errors visible for debugging. This selective filtering is powerful for data cleaning while maintaining error visibility.

Implement Graduated Error Responses

Create tiered error handling that responds differently based on error severity. Treat #REF! and #NAME? as critical (invalid formula structure), #N/A and #DIV/0! as data issues (fixable by users), and #VALUE! as input problems. Route critical errors to immediate alerts while logging data issues for batch review.

Use with Data Validation for Input Control

Combine ERROR.TYPE with data validation to prevent users from entering formulas that produce specific errors. Create validation rules that reject #DIV/0! or #VALUE! errors while allowing #N/A (acceptable for incomplete lookups). This proactive approach prevents error propagation in shared workbooks.

## When to Use ERROR.TYPE

✅ Need to identify specific error types
✅ Building custom error messages
✅ Creating error-logging systems
✅ Conditional logic based on error type
✅ Audit trails requiring error categorization

## When to Use Alternatives

**Use ISERROR when:**
- You only need TRUE/FALSE (is this an error?)
- Simple error detection without categorization
- Performance is critical (ISERROR is slightly faster)

**Use IFERROR when:**
- You want to hide errors and show alternatives
- Error type doesn't matter, just suppress it
- Cleaner syntax is priority over error identification

**Use ISNA when:**
- Only checking for #N/A errors specifically
- VLOOKUP/MATCH error handling
- Distinguishing #N/A from other errors

## Combining Functions

The most powerful approach often combines ERROR.TYPE with other error functions:

```excel
// Check if error exists, then identify type
=IF(ISERROR(A1),
    "Error code: "   ERROR.TYPE(A1),
    A1)

// Suppress all errors except specific types
=IFERROR(
    IF(ERROR.TYPE(A1)=7, "Lookup failed", A1),
    A1)
```

## Performance Considerations

- ERROR.TYPE: ~0.001ms per cell
- ISERROR: ~0.0008ms per cell
- IFERROR: ~0.0009ms per cell

For datasets under 100K rows, performance differences are negligible. Use the function that best fits your logic requirements rather than optimizing for microseconds.

## Frequently Asked Questions

### Q1: Why does ERROR.TYPE return #N/A for valid values?

**A:** This is intentional design. ERROR.TYPE returns #N/A to indicate "no error detected." If you need a text message for valid values, wrap it in IFERROR: `=IFERROR(ERROR.TYPE(A1), "No error")`.

### Q2: Can ERROR.TYPE detect custom error messages?

**A:** No. ERROR.TYPE only recognizes Excel's seven built-in error types (#NULL!, #DIV/0!, #VALUE!, #REF!, #NAME?, #NUM!, #N/A). Custom text like "Error: Invalid input" is treated as a valid text value.

### Q3: Does ERROR.TYPE work with array formulas in Excel 365?

**A:** Yes, but with limitations. ERROR.TYPE evaluates each cell individually, so `=ERROR.TYPE(A1:A10)` returns a single result for A1, not an array. Use `=MAP(A1:A10, LAMBDA(x, ERROR.TYPE(x)))` for array processing.

### Q4: Is ERROR.TYPE affected by regional settings?

**A:** No. Error codes (1-7) are universal across all languages and regions. However, error type names (#N/A, #DIV/0!, etc.) may display differently in localized Excel versions.

### Q5: Can I use ERROR.TYPE in conditional formatting?

**A:** Yes. Create rules like `=ERROR.TYPE(A1)=2` to highlight #DIV/0! errors specifically, or `=ISERROR(ERROR.TYPE(A1))` to highlight cells with any error.
