Use Excel Macro in Access

[bharat]

Hi
I wrote an excel macro that works perfectly but only runs for 30,000 records. I need more than that and I have all my data in MS Access.

How can I convert this macro to Access? For your information, I have attache the entire macro. Any help is highly appreciated. Thank you
