Hello,

How do I:

1) delete all blank lines from my input text file
2) My data is in 2 columns separated by space. Like:
    Data1          Data2
   
    Data3          Data4

    I want to make it a comma separated file. That is delete the spaces between the data and make it delimited by comma.

The output will be like:

Data1,Data2
Data3,Data4
(Blank lines deleted and a csv file)

Thanks

Directly from the command line :

for /f "tokens=1-2" %a in (source.txt) do (>>source.csv echo %a,%b)

In a batch :

for /f "tokens=1-2" %%a in (source.txt) do (>>source.csv echo %%a,%%b)
