Friends who often use Excel may encounter some error value information that looks indefinitely: for example, # n/a! , #VALUE! , #DIV/o! Wait, there are many reasons for these mistakes, do you really know them, how do you handle these mistakes? Here are some common mistakes and how to solve them.

1. #####！

If the cell contains a number, date, or time that is wider than the cell, or if the cell's datetime formula produces a negative value, a #####! is generated. This looks relatively simple, we should all understand it.

Workaround: If the cell contains a number, date, or time that is wider than the cell, you can modify the column width by dragging the width between the lists. If you are using the 1900 date system, the date and time in Excel must be positive. If the formula is correct, you can also change the format of the cell to a non date and time type to display the value. (Figure 1)

2. #VALUE!

An error value is generated when you use an incorrect parameter or an operation object type, or when the Formula AutoCorrect feature does not correct the formula #VALUE!. This includes mainly 3 reasons.

1 If you enter text when you need a number or logical value, Excel cannot convert the text to the correct data type.

Workaround: Confirm that the formula or function requires the correct operator or parameter, and that the formula refers to a cell that contains a valid number. For example, if cell A1 contains a number and cell A2 contains text, the formula = "A1+A2" returns the error value #value!. You can add these two values with the SUM worksheet function (the SUM function ignores text): =sum (A1:A2). (Figure 2)

2 Enter the cell reference, formula, or function as an array constant.

Workaround: Verify that the array constants are not cell references, formulas, or functions.

3 Assign a numeric range to an operator or function that requires a single numeric value.

Workaround: Change the range of values to a single value. Modify the range of values so that it contains the data row or column in which the formula is located.
