Dumping massive data to a SST29EE020 EEPROM

I need to dump a big amount of data into two EEPROMs SST29EE020.

My two questions:

a) Not having a programmer available, using a PIC to burn the data, is it the only way? Any other alternatives? Besides my testing to learn how to use them, never programmed any external EPROM / EEPROM.

b) The data going into the EEPROMs I will generate, most probably, with Excel.

I know I did in the past but for the life of me I can't recall how I managed to move it inside the PIC separated by commas as required to be saved as data, like this:

DB 233, 244, 28,87, 98

Or was Notepad with tables saved in a RTF ior .txt file?

I intend to express values in decimal.

Just a word: this application is just to complete a project and I would like a "sure fire" procedure to avoid experimenting. Please help me on this.

Gracias to anyone with concrete ideas.

The right solution is to make bridge where PIC or any other CPU will be connected one side to PC via USB or RS232 port to take data and other side to EEPROM to write data to. There are some open source projects but some programming will be required anyway.
Based on questions you ask I assume you are not embedded programmer (if at all). So my suggestion is to use any of widely available USB programmers. Look for SUB-20 for instance or Ponyprog.
