Why can't the automatic sum of vertical columns in Excel fail?

The reasons why the automatic sum of Excel vertical columns cannot be calculated are: wrong selection area, incorrect format, hidden cell formula error, circular reference function, too many nested precision limits, plus sign ( ) replaced with hyphen (-), blank space Or the newline character Excel version is too old

The reason why Excel cannot automatically sum the vertical columns

Reason 1: Wrong selection area

• Make sure you have selected the entire vertical column that needs to be summed, including numerical values ​​and empty cells.

Cause 2: Incorrect format

• Check whether the cell format is correctly set to "Number" or "Currency" format.

Cause 3: Hidden cells

• Hidden cells will not be summed. Make sure the required cells are visible.

Cause 4: Formula error

• Check whether the summation formula is correct. The typical formula is "=SUM(A1:A10)", where "A1:A10" represents the vertical column area required to be summed.

Cause 5: Circular Reference

• Make sure the sum formula does not create a circular reference. For example, if cell A1 contains the formula "=SUM(B1:A1)", a circular reference is created.

Cause 6: Too many functions are nested

• Avoid nesting too many other functions in the summation function. This may lead to calculation errors.

Reason 7: Precision Limitation

• Excel has a precision limit, which is the maximum number it can handle. If the sum exceeds this limit, a "#NUM!" error may occur.

Cause 8: The plus sign ( ) is replaced with a hyphen (-)

• When entering a value in a cell, the plus sign ( ) May be accidentally replaced with a hyphen (-). Make sure there is the correct plus sign before the value.

Cause 9: Blanks or newlines

• If there are blanks or newlines in cells, the sum function will ignore these cells.

Cause 10: The Excel version is too old

• Some sum functions are only available in newer versions of Excel. Make sure you are using the latest version of Excel.
