Hi, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
I am very sorry about your issues. What email service are you using? Gmail? Hotmail? Yahoo Mail? or others?
Also, how do you access your email? Using a web browser like Internet Explorer? Or are you using an email program like MS Outlook 2010?
Please let me know by replying to me here so that I can help you further.
Thank you for writing back with that information.
Did you delete the spreadsheet on your ipad or on the PC? Was it an attachment to an email message?
If it was just a file, not an attachment, then you need external tool to recover the deleted file.
If it was an attachment to an email and you deleted the email including the attachment, then you can go to the Trash folder and restore the email.
Please let me know so that I can assist you further.
