Frustrating Formula, Need Help!

[scliollio]

Hey there,

Basically I have a tedious routine process that I think can be simplified by having excel do it for me in a formula. Only issue is that I'm not too great with these.

Any help would be greatly appreciated!!

The process is as follows:

• I receive a spreadsheet everyday with many columns of data (~20), but I'm only concerned with a few of them
• Everyday I must compare the "new" report with the "old" report
• There is a unique field called "KEY ID" , a value field called "GSV", and another field called "Tank"
• I manually go through and look for new KEY ID's (ones that appear on the new but not the old), if there is a new one, then it must be inserted directly below the previous KEY ID
• Also if any of the GSV's have changed, then I must copy all of the "New" data (the ~20 fields) and paste it over the "Old" data (basically replace the line of data)
• You cannot simply copy and paste all of the new data over the old data because they are sorted by tanks and it must remain in the order of the "old" (with the exception of new IDs being inserted)

Surely there is a formula(s) which can do this!

Essentially I need the formula to do the following

1. Compare Line 1 "KEY ID" OLD with Line 1 "KEY ID" NEW
2. If KEY ID's are different, insert new KEY ID and all associated data from NEW doc below Line 1
3. If KEY ID's are the same, compare GSV values, if GSV value's differ, replace OLD docs line 1, with NEW docs line 1
4. Repeat steps 1-3 for next line (continue to repeat until finished)

Attempting to type an example:

	OLD		NEW
	Tank	Key ID	GSV		Tank	Key ID	GSV
	1001	566	11,514.60		1001	566	11,684.20
	1002	532	19,549.80		1002	532	19,549.80
	1003	544	8,557.40		1003	544	8,557.40
	1004	589	14,522.40		1003	545	9,025.10
	1004	566	21,901.50		1004	589	14,522.40
	1006	502	12,156.80		1004	566	21,901.50
					1006	502	12,036.70
					1006	503	14,177.60
