vvraj,
For that number of rows, would it not be easier to switch to a database
program ?

Dear All,

I am beginning to learn & code in VBA.
Can anyone help me with this? How to write a macro to

1. read about 300,000 rows/records from multiple worksheets from the
same workbook.
2. for each record read, some processing/calculation is done based on
some fields in the record.
3. write back with the updated record with the computed fields to
another workbook with multiple worksheets.

(Assume each worksheet is to hold maximum of 60,000 records/row)

How would the code differ if I would were read from a text file,
compute and write to a workbook with multiple worksheets?

Thanks in advance
vvraj
