I can type about 70 characters in 1 minute, so I think can finish your job as fast as I can. In the first, I will finish importing those data as fast as I can. And then I will check all the data twice that was imported in the second day whether they are all correct or not. For the data checking, I will check all the data whether they are correct or not by comparing with original one. For the function checking, except checking the function is correct or not, I will also use another method to check the result by using the basic calculation or others. Although I am a beginner in the website, I can promise that I will do this project as perfect as I can by using all the skills I have in Excel and the skill on checking.
