 # How to use IF, ISNA and VLOOKUP function in Excel?

In this article, we will learn how to use Excel ISNA function with VLOOKUP to ignore the #N/A error while calculating the formula in MS Excel 2016.

Excel VLOOKUP function is used to look up and fetch data from a specific column of a table. The "V" stands for "vertical". Lookup values must appear in the first column of the table, with lookup columns to the right.

## How to use the Vlookup function in excel?

VLOOKUP function in Excel is used to look up and retrieve data from a specific column of a table.

Syntax:

 =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])

## How to use the ISNA function in excel?

ISNA function used for checking the #N/A error while calculation by using any function.

Syntax:

 =ISNA(Formula)

## How to use the if function in excel?

IF function works on logic_test and returns values based on the result of the test.

Syntax:

 =IF(Logic_test, [Value_if_True], [Value_if_False])

Let’s get this with an example.

Here we have two sheets, we have to get the BIRTHDT from SHEET 1 table to SHEET 2 Table using the functions.

Write the formula in C2 cell of SHEET 2.

 =IF(ISNA(VLOOKUP(A2,Sheet1!A:F,6,FALSE)),”NotFound”, VLOOKUP(Sheet2!A2,Sheet1!A:F,6,FALSE))

Explanation:
Vlookup function in excel looks for the 6th column of the SHEET 1 matching  REC_ID in SHEET 1 from SHEET 2.
ISNA function in excel looks for the #NA error and passes it on to IF function.
IF formula in excel checks if any #NA error occurs, it print “NotFound” instead of the #NA error.

Copy the formula in other cells, select the cells including the first cell where the formula is already applied, use shortcut key Ctrl + D. As you can see in the above image, the formula is working fine. And the user can work without getting irritated by #NA error.

IF Statement combining multiple 'IF TRUE' conditions

Assuming that I have a worksheet with columns A,B,C and D on it, now I want an IF statement in column E which follows this argument:
IF A1 is "0" or "N/A", then show N/A, but if A1 is any other number, then B*(C+D)
I hope that's easy to follow. I have tried so hard to get this to work but just can't.
As ever, any help would be hugely appreciated.

## Users are saying about us...

1. Is there a way to get a vlookup to replace an NA from another vlookup? I have 2 sheets, one is hr and one is our data, hr has the updated info and ours have some lines that the hr file does not. when searching for the changes, I do want to pull in information so it will be easier to copy and paste but I need all the info in a combined sheet that works automatically. I have it so it pulls in the HR data but I need all the nas to fill in with our data if they appear. Please tell me this is possible!

• Yes, of course, you can do it. Just wrap the first Vlookup with the IFERROR function. on the error part, put another VLOOKUP formula.
Like this. IFERROR(VLOOKUP(lookupValue,table1,col,0),VLOOKUP(lookupValue,table2,col,0))
