Excel 条件格式以识别时间值而非数值的值

Question

I need to use conditional formatting to either: -

1. Identify time values in a sheet which should only contain numeric values or
2. Identify any cells that aren't numeric values (not 100% on this as time values possibly stored in similar to numeric values).

I'm looking around and experimenting all morning but I can't nail it down.

Any help much appreciated, thanks.

Edit: For reference, this answer does not answer my question, as I'm trying to identify cells that contain time values, rather than simple numeric values.

Answer 1

If you use the following formula as a conditional formatting rule it will then highlight the cells that are time values.

=TIMEVALUE(TEXT(C3,"hh:mm:ss"))     

In testing I have had to create the rule on a cell that is already a number value and then apply it to every other cell as it was changing the format of time cells to their underlying number if done otherwise.

Create a new conditional formatting rule for cell C3 with the above formula as the rule.

Then when applied, right click the cell and copy, then select the range of cells you want to apply the format to and select Paste Special - formats.

This should then hightlight any value that has a time format
