I have a nested IF formula. The return value for some of the IF statements is given by index-matching. If the item doesn't exist on the other sheet, the index-match returns a #N/A, but if there's an error I want the cell to say "Needs Investigation" instead of #N/A, so I've put in IFERROR statements to do this. This works fine. See the first IF statement I have emboldened to see what I'm talking about.

The issue I'm having is with the last IF statement (also in bold). This one is different from all the other because it has multiple conditions (one of which is given by index-matching) and because I specify an Else return value (i.e. If condition is true, then return value, else return other value). I want to achieve the same thing as above (that is, if the same #N/A error occurs as above I want the cell to say "Needs Investigation" instead of #N/A). I've put in IFERROR statements everywhere I can think of, and nothing works. Where should I be putting in IFERRORs? Or should I be using something other than IFERROR?

=IF(D2="Approved","Approved",IF((AND(D2="Supplier Submittal",E2="Interim Approval")),"Interim Approved",IF(D2="Define","Initial Review",IF(D2="Due Date Approval","Initial Review",IF(D2="Initial Review","Initial Review",IF(D2="No Status","Drawing Not Released",IF(D2="Polaris Review","Polaris Review",IF(D2="Staging","Waiting on Child Components",IF(D2="Supplier Acceptance","Initial Review",**IF(D2="Closed W/O Approval",IFERROR(INDEX(SharePoint!X:X,MATCH('Exceptions List'!A2,SharePoint!N:N,0)),"Needs Investigation")**, IF(D2="Needs Validation",IFERROR(INDEX(SharePoint!X:X,MATCH('Exceptions List'!A2,SharePoint!N:N,0)),"Needs Investigation"),IF(D2="No PPAP Required",IFERROR(INDEX(SharePoint!X:X,MATCH('Exceptions List'!A2,SharePoint!N:N,0)),"Needs Investigation"), IF(D2="Transferred",IFERROR(INDEX(SharePoint!X:X,MATCH('Exceptions List'!A2,SharePoint!N:N,0)),"Needs Investigation"),IF((AND(D2="Supplier Submittal",C2<TODAY())),"Supplier Late",IF((AND(D2="Supplier Submittal",C2>TODAY(),C2<$J$1)),"On Track for PV",**IF((AND(D2="Supplier Submittal",C2>$J$1, INDEX(SharePoint!X:X,MATCH('Exceptions List'!A2,SharePoint!N:N,0))="")),"Due after PV",INDEX(SharePoint!X:X,MATCH('Exceptions List'!A2,SharePoint!N:N,0)))**)))))))))))))))

Here's the same formula, probably easier to look at.

If it helps, here's an example of the the first IF statement I emboldened (the one that works)
from the spreadsheet.

And here's a snapshot of an example of the IF statement I'm
having trouble with.

Using the SWITCH function may help in debugging the issue by making the formula more readable and easier to maintain. The parentheses have been reduced by 15 sets including the outer sets surrounding the (AND(...)) functions.

Because there is still IF nesting in the "Supplier Submittal" case requiring a default action (the last nested IF's FALSE condition), this default was also duplicated to the SWITCH function's default clause. These defaults INDEX(MATCH()) are now bracketed by IFERROR. The lack of IFERROR here likely caused the #N/A error.

The potential for an uncaught #N/A error in the INDEX(MATCH())="" test to determine a "Due after PV" condition could be fixed locally by returning something other than "" like this AND( C2>$J$1,IFERROR(INDEX(MATCH()),"NO MATCH")=""), "Due after PV",. Having this IFERROR return "Needs Investigation" would also make the comparison to "" FALSE causing this final IF's FALSE condition, IFERROR(INDEX(MATCH()),... to return "Needs Investigation".

The implemented solution was to bracket this entire final nested IF ("Due after PV") in the IFERROR and removing the redundant IFERROR from this IF's FALSE condition.

Occasionally Excel likes to paste multi-line formulas into multiple cells. In this case, paste the formula directly into the formula bar.

The formula (bar) can be formatted with line breaks by pressing Alt-Enter
