What format are the original (5) files in?Are they text, csv, or excel files?
What is the relationship between the 90,000 records and the other 5 files?That
is, do the records show up once in the list of 90,000 and show up multiple
times in the 5 files?What are the "key" field? (those in common that "relate"
the two records?)For instance, an "Order Number", or ??
First: for a set of records of this size, I would NOT use vlookup.The problem
with vlookup is that it executes each time a "calculation" is done on the
workbook, even though it already has an answer.
So, if you have 90,000 vlookups, and change the heading, it executes 90,000
times.
I would definitely use a Dictionary object.
HOW I'd use it would depend on the relationship between the files
If you could send me some sample files, I'd be glad to throw something together
for you to look at.

Subject: $$Excel-Macros$$ Query for Paul
Hi Paul,
I need your Suggestion Basically I have a master file having Approx 90,000
Orders no in this Sheet. From 5 Files I need to fetch the Data Corresponding to
that Orders nos Ya Columns value, Each file has specific data related to master
Orders nos, Manual Vlookup i can use I know that to get the data from files,
Now I want to automate this process Which is the fastest way to get the data
from all file Please suggest the correct one
1. Whether i should use vlookups in the VBA to get the data present in others
files corresponding to order no, 2. Do i need to use Loops for efficient
checking of data 3. Should i use Dictionary object and store the orders no and
use this techniques.
I know how to do this but Still looking for the faster one.
