Getting on the waiting list does not happen automatically. Make sure your nephrologist knows you want a transplant, and that however it happens, you do actually get referred to a kidney transplant center.
CSV (Comma Separated Value) was a file format devised to store tabular data. It uses commas to separate each entry in a row and the newline symbol to go to the next row. Excel is a more recent spreadsheet application from Microsoft and it saves the data with its own file format. Excel is way more superior compared to CSV as it is able to do a lot more to the tabular data. Formatting is one of the biggest feature that comes with newer spreadsheet applications.
A CSV is a comma separated values file which allows data to be saved in a table structured format. CSVs look like a garden-variety spreadsheet but with a .csv extension (Traditionally they take the form of a text file containing information separated by commas, hence the name). CSV files can be used with any spreadsheet program, such as Microsoft Excel, Open Office Calc, or Google Spreadsheets. They differ from other spreadsheet file types in that you can only have a single sheet in a file, they can not save cell, column, or row styling, and can not save formulas.
