wps excel VLOOKUP function has no valid # N / A does not match the display out of solution
First, if the value that does not exist in the displayed Look # N / A, to check whether there is other additional character spaces on both sides as a result of inconsistent data .
If it is determined there is data and consistent data, that data is probably not the same type of lead, we mainly talk about this issue.
I use WPS, select the cell can right-click format cells, but not so simple, both sides at the same time as text or numbers will not work, because setting a time inside the cell will not change the content, you need only double-click change come.
Column D as in FIG. I after all set to the value, and then double-click will be converted into a numerical format as the first image.

So if there are a lot of how to do, it is impossible to double-click one ah.
This selected column and click data → disaggregated, the pop-up dialog box, select {TAB} key "next" → Select [delimiter] "Next" [General] → Select "Finish." Of course, if the batch is converted into text format on selected text.
