@Sp3ctre1 please add more details, adding your current query used to create transaction would help!
What is the field name of each column that you need including the first one with masked data?
Also add a mock up of the final output you need. Do you need to split each column into two new columns? What would be the column names after you split? Would you split even the first column with data masked?
