Okay i pretty new to Excel (office version 2003) , i need to make and save
some tab delimited files , No probs , but when i load them back up , for
example a long number such as :- 5031366015174 saves okay and is fine in its
delimited text file , but when i load the tab delimited file back into excel
the long number has become 5.03137E+12 , so when i save it again after
adding more data to the list , the number is no long any use ?!?! any way to
stop this please.

When i load the file back into excel i choose delimited , file origin
ms-dos(pc-8), delimiter tab,column data general , all other boxes unticked ,
these are the standard defaults.

Its driving me round the twist , as the data saved is okay the first time ,
but when you load the data back up into excel the long number is useless?

Any help or advice please
