Corrupt file iPhone application

I have a spreedsheet file that i have been creating for the last 9 months. i have been using my iPad to creat this file and i have been using the Numbers app, an ios app. To my dismay, this file is corrupt. i need someone that can help me revive this file and bring it back to work. when I tap on the spreadsheets to open it, I see the 'opening spreadsheet' bar scrolling, then the screen disappears and reverts back to the main screen showing my application icons. if you can work on this file and put it back to work, please get in touch with me on how to send you the file. thanks
