I have seen many algorithms and formulas for converting RGB data to HSL but none were successful.
So where can I get few algorithms/formulas for converting.

If you only need to convert values by hand, then you can use this tool: http://colormaid.com/color-conversion/ – zovits Apr 02 '15 at 16:56

How did you decide it is not working? Are you sure your value ranges are correct? – Ali Naci Erdem Apr 06 '15 at 10:06

If performance isn't critical, the above link is a good example.
If you need it to be several times faster than a pure C implementation of the above, you can do it with SSE instructions. An example of RGB to HSV is in the ahsv_from_argb_sse2 function at: (EDIT: Updated link)

Converting to HSL is not all that much different. You can see the difference in the code at:
