Convert a two-column list into a csv

Hi experts,

I have a very large (1.5M lines), sorted but unstructured list that looks like this:

Code:
process_nameA    valueA
process_nameA    valueA
...
process_nameB    valueB
process_nameB    valueB
...
process_nameN    valueN

I'd like to turn this into a csv.

The values are all numerical and can be different. I've been using a bunch of shell commands strung together to manipulate the data to a format I have now, so it would be great if it's possible to pop another shell command onto the end of what I already have to accomplish this.

Code:
process_nameA,process_nameB,...,process_nameN
valueA,valueB,...,valueN
valueA,valueB,...,valueN

Thank you!

irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
