This is a very simple and naive program written in C that converts a space/tab separated values text file into a comma separated (csv) file and back, very straightforward.

This program was written as class project for a Systems Programming course, while learning the basics of the C programming language. The original code converted files from CSV to several made-up format and back.

I needed to convert a txt file to csv for another project and for some reason this project came to mind first before searching Google. The program now has been refactored and cleaned up.

You will need a C compiler on your system. Must Linux distros and, I believe, macOS (or other UNIX system) come already with a C compiler ready to use.

Windows:

• Install C Compiler on Windows
• or, install the C/C++ Development Support for Visual Studio

File Format:

• .CVS: comma-separated values
• .TXT: space/tab separated values (^[a-zA-Z0-9]\t*\n*)

You can simply run the application directly from Visual Studio (if on windows) or you could use the Developer Command Prompt for VS/Developer PowerShell for VS that comes with Visual Studio (not sure since which release but definitely on 2022)

cl .\txt2csv.c
.\txt2csv.exe

Linux/macOS:

gcc -o txt2csv txt2csv.c
./txt2csv
