Notepad++ convert multiple lines to a single line and vice versa

Notepad++ is an awesome text editing tool, it can accept regex to process the text data.

If the data is in a “.csv” format or comma separated values which is basically just a text file that can either be opened using a text editor, excel or even word. Notepad++ can process the contents of the file using regex.

Example if the data has multiple rows or lines, and what is needed is to convert the whole lines of data into a single line. Notepad++ can easily do it using regex.

However, if the data is on a single line and it needs to be converted into multiple lines or rows then regex can also be used for this case.

Here’s an example on how to convert multiple rows or lines into a single line.

Example data:

Multiple rows, just a sample data.


Press Ctrl+H, and  on "Find what" type: [\r\n]+ and on "Replace with" type with: ,(white space) --white space is needed if need to have a space in between the data.

See image below, "Regular Expression" must be selected and click "Replace All" once done.



This is the image after clicking "replace all", if everything works fine.



To do the other way around, or single column to multiple rows then do this method.

On "Find What", type: \r\n and on "Replace With" type: , 


Final output after clicking "Replace All".


That's it, Notepad++ and Regex works hand in hand and does wonders. It saves time and make life easier.


Cheers. Till next time.

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username. WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided. Why would you need a command line tool if there’s a GUI to check? If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username. If you have remote computers, you need to delegate someone in the remote office or location to check. Or you can just write a batch file or script to automate the task. Here’s the code below on how get computer model, manufacturer and the username.

The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only.
