We have 4 large csv files that need to be converted from the following format Symbol, Date, Open, High, Low, Close, Volume To Date, Percentage Change (but with Symbol as the heading) Where Dates will be normalised from 1st of January 1999 to end of December 2018 for all, missing values will be zero and where Percentage Change is equal to ( ( Close / Open ) - 1 ). CSV files are too large for excel and contain more than 1million rows. Should be a relatively easy scripting job. There is an example input table and output table.

Dear Employer, I understand you need to change the format and apply percentage But as the size is too big, I would probably need to upload data in Db first, change everything there and then download it. So its more work that ways. Do try me once :) Thanks and Regards, Ash
