Python master to do data table manipulation and organization

Actually I already have a python program to do this but this is too slow and error prone.

Since I already have a program, it will be easy for you to compete it.

The program does "Change the column x of file X (usually tab-delimited txt) to column y1 of file Y if column x of file X is in column y2 of file Y"

But this program causes "memory error" with large files especially when the output file is xlsx and too slow.

I hope you have good understanding and carefulness.

I will tell you more story after you post message.

Yeah, parsing! Here's the key: sounds like the file is being entirely loaded into memory vs utilizing a filepointer. No payment required until you're happy. Based in Toronto.
