Hello,

I have a .txt file with 17,000 records. When I update/modify one or
two records, I would like to export the updated/modified records into
a new .txt file that i can upload to my online store.

Is that possible?

What I am trying to accomplish is keeping an offline database of
inventory I have in my online store. There is no need to update the
entire .txt file if I only need to change one or two records. Perhaps
there is an easier way. I don't want to 'link' to the online file. I
want the data I am working on completely off line.

thank you.
David
