This document discusses common Excel error messages including #DIV/0!, #NAME?, #N/A, #NULL!, #NUM!, #REF!, #VALUE!, and #####. It provides examples of how each error can occur and steps to resolve them such as checking for invalid cell references, non-numeric arguments, missing values, or adjusting column widths. Common causes include formulas with division by zero, misspelled function or range names, text in formulas, unavailable values, invalid numbers, deleted cells, mismatched argument types, and small column widths.

Excel error

2. Excel Error
There are eight different error messages in Excel:
i. #DIV/0!
ii. #NAME?
iii. #N/A
iv. #NULL!
v. #NUM!
vi. #REF!
vii. #VALUE!
viii. ##### error
The error message that you are presented with, provides information
about the type and cause of the Excel formula error. It can therefore
assist you in identifying and fixing the problem.
3. i) #DIV/0! error
The Excel #DIV/0! is produced when a formula attempts to divide
by zero. Clearly, a division by zero produces infinity, which cannot
be represented by a spreadsheet value, so Excel returns the #DIV/0!
error.
Change the value of cell A2 to a value that is not equal to 0.
4. ii) #NAME? error
The #NAME? Error occurs when Excel does not recognize text in a
formula. When Excel encounters text in a formula, it will try to
interpret the text as a reference, a named range, or a function name.
If the text is not recognized as any of these, the #NAME? error will
be generated.
Therefore, the way to approach a #NAME? Excel function error is
to check your function names, references and named ranges have
the correct spellings, and check that any variables that are meant to
be text values are entered in double quotes. If your formula
contains nested functions, check the results of these individually,
until you identify the source of the error.
6. iii) #N/A Error
The #N/A Excel formula error is produced when a value is not
available to your formula.
For example, the example below shows an attempt to use the
Vlookup function to find the value "Cabbage" in column C of the
spreadsheet, and return the associated cost from column D.
However, as "Cabbage" does not appear in column C, the
VLOOKUP function is unable to find this value and so returns the
#N/A error.
7. Therefore, in order to get to the bottom of a #N/A error, you
need to look at the values that the formula is accessing and
identify why the required value is not available.
8. iv) #NULL! Error
It occurs if
• Multiple cell references in a formula are separated by a space instead
of a mathematical operator such as a plus sign ( + ) - example: =A1
A3+A5;
• The start and end points of cell ranges are separated by a space instead
of by the range operator - the colon ( : ) - example: =SUM( A1 A5);
• Individual cell references in a formula are separated by a space instead
the union operator - the comma ( , ) - example: =SUM( A1 A3,A5);
• The intersect operator - the space character - is used intentionally, but
the specified ranges do not intersect - example: =SUM(A1:A5 B1:B5)

10. v) #NUM! Error
The #NUM! Excel formula error is generated when Excel
encounters an invalid number in a formula. For example, all square
numbers are positive, so there is no such thing as a square root of a
negative number (unless we enter the world of imaginary
numbers). Therefore, the Excel function SQRT(-2) will generate
the #NUM! error, to indicate the invalid negative number argument
to the square root function.
11. Therefore, the way to fix a #NUM! error is to check each of the
numeric arguments in your formula. As with the other argument
types, if your formula is nested or built up of multiple parts, it is a
good idea, to break down the formula and evaluate each argument
separately.
12. vi) #REF! error
Excel displays the #REF! error when a formula refers to a cell
that is not valid.
1. Cell C1 references cell A1 and cell B1.
2. Delete column B. To achieve this, right click the column B
header and click Delete.
14. 4 To fix this error, you can either delete +#REF! in the formula of
cell B1 or you can undo your action by clicking Undo in the
Quick Access Toolbar (or press CTRL + z).
15. vii) #VALUE! error
Excel displays the #VALUE! error when a formula has the wrong
type of argument.
1a. Change the value of cell A3 to a number.
1b. Use a function to ignore cells that contain text.
16. viii) ##### error
When your cell contains this error code, the column isn't wide
enough to display the value.
1. Click on the right border of the column A header and increase the
column width.
17. 2) Double click the right border of the column A header to
automatically fit the widest cell in column A.
