Dear,
I am an Excel expert and speak English fluently. While I don't have 100's of reviews like a couple of other bidders I have seen for your project, I invite you to have a look at the reviews I received for the projects I have already completed through freelancer.com. I have also been rehired a couple of times.
Regarding your project, let's have a look together and I am confident we can solve this very fast. I know numbers are a pain in the *** in Excel because they can have all kinds of peculiar formatting, including the ones you mentioned.
Don't look further, I will be available the next couple of hours and will not let you down. If you award me with this project, you can count on further assistance after completion of the project, of course without any extra cost if it's within the scope of this project or for any minor amendment.
Many thanks in advance for your consideration and best regards,
Michael
