Depending on the format of the original data you may or may not
be able to recover the codes; for example 08E281 would give
the same number as 80E280, so if both of these are possible
you couldn't distinguish them.

If the format is always abExyz
where a,b,x,y,z are digits and a < 0 then this formula should work:

=SUBSTITUTE(TEXT(A1,"00E+000"),"+","")

(assuming value to be converted in A1)

Hi.
I have received a file and some of the customer # has been changed as
scientific notation.

8.50E+281
like so. I went format CellText and it doesn't convert back to text.
I have also tried Text column text and it still remains the same. Is there
a way to restore what it used to be? It's supposed to be 85E280.

THANK YOU!
