UPloading LC-MS cleaned - processed data from excel for PCA analysis

Hey, good day…
I have my LC-MS data in an excel sheet and have done a lot of processing in excel (e.g normalising, filtering etc), now I would like to do PCA in order to identify the outlier. My data are from a clinical trial (treatment and placebo group) with blood taken at different time points. Unfortunately, I have never used MetaboAnalyst someone just informed me to check it up. Now that when I tried to upload my excel datasheet it is not going through. How do I upload this data and do PCA analysis and identify outliers? Thankx very much…

There are details on this on our data format page. You can also look at the example datasets: each module has example data, and if you click on the dataset name hyperlinks, you can view the format.
