help with updating spreadsheet

[JAZZNAURA]

hi all,

I’m new to excel and learning as i go. i need help, I’m trying to make
my work a bit easier. i want to keep a historical record of products
and there locations at work (work in a warehouse by the way), I’ve
managed to create a worksheet (see below, worksheet 1) that uses
vlookup (=VLOOKUP(Sheet1!A:A,Sheet2!A:B,2, FALSE)) to get a list of
about 4000 products and there locations from worksheet 2, worksheet 2
is updated daily by importing a text file.

what i can't figure out is how to update work sheet 1 using a
formula/macro, one that updates the location of what’s already on the
list (list is column A) in the next empty "location" column (in this
case column C) and if that product number is no longer on the list on
sheet 2, leaves the cell under column C blank or ******. Also, adds
any new product numbers at the bottom of the list in column A (no
duplicates) and the location in the next free "location" column (in
this case column C), but leaves all data already in the worksheet
(historical record).
I’m happy to paste formulas on a daily bases to the next free column if
it is difficult.

I hope I explained what I’m after clearly; any help anyone can give me
would be gratefully received.

Please remember I’m new to this and may need it explained as simple as
possible

Thanks again

Hello,

I don't have time to do the whole thing, but here are some thoughts...

what i can't figure out is how to update work sheet 1 using a
formula/macro, one that updates the location of what’s already on the
list (list is column A) in the next empty "location" column (in this
case column C) and if that product number is no longer on the list on
sheet 2, leaves the cell under column C blank or ******.

My suggestion would be to insert the new days data into column B each time,
with older data moving to the right. This makes building the macro much
easier as it doesn't need to work out which column is the next blank column -
just use the macro recording tool to record inserting a new column and
copying the formula in from column C (was column B). Then copy column C and
use paste special/values to remove formula but retain data, so vlookup
doesn't continue to update this column with new values, then update text file
data in sheet2.

Keep in mind that at some stage you will need to archive old data as it will
only take 256 work days before you run out of columns.

Rather than having an N/A error returned when the vlookup can't find the
right product in sheet 2, use an if statement with ISERROR formula to check
for discontinued items. Something like...

=IF(ISERROR(VLOOKUP(Sheet1!A:A,Sheet2!A:B,2,
FALSE)),"******",VLOOKUP(Sheet1!A:A,Sheet2!A:B,2, FALSE))

Also, adds
any new product numbers at the bottom of the list in column A (no
duplicates) and the location in the next free "location" column (in
this case column C), but leaves all data already in the worksheet
(historical record).

To find new records in sheet2, I would do a vlookup the other way in sheet2,
and filter for N/A errors, where vlookup can't find a match for that part
with the table in sheet1. These values could then be copied to the bottom of
sheet 1.

I’m happy to paste formulas on a daily bases to the next free column if
it is difficult.

To be honest, this would be way easier in Access and you wouldn't have to
worry about running out of columns. If you can get your employer to spring
for introductory Access course, it's not that difficult after that. If you
figured out vlookup-ing yourself, you should be able to pick up Access OK.

possible

You had a lot of questions in your post. You might get more replies if you
broke it down into several posts.

Cheers,

Glen
