I have a list which contains seven digit numbers with around 30 columns and
3,000 rows approximately. Not all cells contain a number - some are blank.

I want to find duplicate numbers in each row and delete them.

For example, I have:

A B C D E
F
1234567 2345678 2584987 1234567 1234567
5896584 2584987 6598475 5896584 1234567 2584987
5897845 5897845 2584987

etc. ...

The numbers are in no particular order and may occur more than once in each
row. In some rows they may occur 20 or more times. They also recur
throughout the worksheet.

What I want to do is delete all the duplicates in each row only, i.e. in the
first row above, where the same number occurs three times, I want to get rid
of two of them and only leave one.

It doesn't matter how the cells end up in regard to the columns, as long as
the numbers stay in the same row, as each row will be concatenated into one
number eventually. Some rows may only have two numbers in them (in the first
two columns) but other rows may have anywhere up to 30 numbers. Each number
has seven digits.

I hope this makes sense and someone can come up with a formula to enable me
to do this easily.

Thank you in anticipation.

Lyn.
