If you have a CSV file that contains empty columns, you may find that the output is inconsistent in Excel. This is because Excel treats empty cells differently than other spreadsheet programs. When you open a CSV file in Excel, the program will automatically detect any empty cells and treat them as if they were filled with the value 0. This can cause problems if you are expecting to see blank cells in your data.
There are a few ways to work around this issue. One is to open the CSV file in a text editor such as Notepad++ and then use the Find and Replace function to replace all of the commas with something else, like a period. This will cause Excel to treat the empty cells as if they were filled with the value 0. Another way to work around this issue is to open the CSV file in Excel and then use the Text to Columns function to split the data into separate columns. This will allow you to see the data in each column separately and will also allow you to delete any empty columns that you don't need.
If you are working with a lot of data, it may be easier to use a third-party program such as OpenOffice or LibreOffice, which can handle CSV files with empty columns without any issues. These programs are free and can be downloaded from their respective websites.
