Assume the amounts, if any, are input in B2 down
while corresponding items are listed in C2 down
(Items in col C are assumed unique)

In D2: =IF(B2="","",IF(NOT(ISNUMBER(B2)),"",ROW()))
Copy D2 down to cover the max expected extent of data in col B, eg down by
200 rows. Leave D1 empty.

Then place
In E2:
=IF(ROWS($1:1)COUNT(D:D),"",INDEX(C:C,SMALL(D:D,R OWS($1:1))))

In F2:
=IF(E2="","",INDEX(B:B,MATCH(E2,C:C,0)))
Select E2:F2, copy down just enough to cover the max expected returns per
any single instance, eg down by 30 rows. Cols E & F will return only the
items with amounts, neatly packed at the top.

I have the following formula to extract data from a long list. The list has
two columns, the first one with amounts, the second one with items. I use
this Array formula to give me in a list onlt the items that have an amount
next to it. I sense that this array is causing my workbook to work slow.
Please let m know if I can use a different formula, database formula, pivot
tables, sort... that will shorten the calcaulation time.

=IF(ROWS(Sheet1!$1:1)<=COUNTIF(First,"0"),INDEX(F irst,SMALL(IF((ISNUMBER(First)*(First0)),ROW(Firs t)-ROW(Sheet1!A$1)+1),ROWS(Sheet1!$1:1)))&"

"&INDEX(Second,SMALL(IF((ISNUMBER(First)*(First0) ),ROW(First)-ROW(Sheet1!A$1)+1),ROWS(Sheet1!$1:1))),"")

"First" is a name range for the column with the amounts.
"Second" is the second column with the items in it.
