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.
Notepad (or any text editor). To create a CSV file with a text editor, first choose your favorite text editor, such as Notepad or vim, and open a new file. Then enter the text data you want the file to contain, separating each field with a comma and each row with a new line. Save this file with the extension .csv.
