sterndata on "exporting by date"

Hello,
I can't seem to figure out how to export my lead form data for just one month (June for example). I want to pull of of my different forms data, which I figured out how to do by using the * symbol to replace one form's name. But I can't figure out how to do that and just for a certain period of time.
Something I read said something about using shortcode, but I can't figure out how to do it exactly. Anyone able to walk me through the steps to do this?

thanks so much

What "lead form"? Are you using a plugin for this? If so, which one?

Sorry, Contact Form 7.

I agree with Dabliu -- that's a great plugin.

Hi and thanks very much for the replies.
I clicked on that link and it takes me to the Contact Form DB page to download it. That is already what I'm using now to export data. So sorry, I just realize I didn't clarify that to begin with. I agree, I love the plug in to export ... but I can't figure out how to set it to just export for a specific time period (like say just June). It exports every form historically entered ... which is a HUGE file to export each month when pulling my reports.
Do you guys know how to use ContactForm DB and pull data for a set period?

thanks again!
