i have a excel .CSV file that Gmail generated for me with my contacts in..
what i want to do is function that go over all the contacts emails one by
one and deletes all missformated addresses that cannot be use to send email
for them.. somthing like :

if (the cell's text is not an valid email address)
{
delete the cell ;
}

to be honest i dont know much about excel so i need somthing from
scratch..

thank you all very much..
 
A quick and dirty check would be to look for the @ character in the cell.

You could insert a new column adjacent to the column with the data and use:

=if(countif(a1,"*@*")=0,"Nope","Maybe")
Where A1 is the cell to inspect.

Drag it down as far as you need.

Sort by this column
Delete the Nopes
and start looking to see if you need better rules.

If you do, you may want to post back with more samples of what your data looks
like (in each cell).
 
You can look for these characters, as well:

()[]\;:,<>@

None are allowed in an email address before the @ sign. Once you find all
of the email addresses without an @ sign and remove them, you could use 'Text
to columns' to split the email address between the local part of the address
(anything before the @ sign) and the domain name (everything after the @
sign). Use the @ sign itself as the delimiter. Then search for the
characters mentioned above in the local part of the address using Dave's
formula.

HTH.

Click to expand...

take all the email adress to spreadsheet and save as macro enabled
xlsm or .xlm and follow below steps. Please refer to attached
spreadsheet for your reference.

Copy the below code.
Open the Excel file in which you want to use the code.
Hit Alt+F11 to open the Visual Basic Editor (VBE) window.
From the menu, choose Insert-Module.
Paste the code into the code window at right.
Save the file and close the VBE
