Extract data from excel

I will not pay more than $15 to have this done so please don't bid if you can't do it for this price or less. I have a very large spread sheet of about 3,000 rows with a list of postcodes in 1 column and a list of postcode zones in the other. I need to extract out postcode ranges based on the Zone. Not all the numbers in the postcode zones are consecutive. The output should be in a text file. For the example below, the output for the DWN range would display like this: DWN~: 0800-0801, 0804, 0810-0813 Consecutive numbers should be seperated with a hyphon and non consecutive numbers with a comma. You should seperate each zone with a pipe symbol. Each output postal range must be specific to each zone. Postcode Zone 0200 CBA 0200 CBA 0221 CBA 0800 DWN 0800 DWN 0801 DWN 0804 DWN 0810 DWN 0810 DWN 0810 DWN 0810 DWN 0810 DWN 0810 DWN 0810 DWN 0810 DWN 0811 DWN 0812 DWN 0812 DWN 0813 DWN I suggest you either do this with VBA or export the info and write a small script Timeframe: 1 day Payment: Escrow on completion (after checking)
