I need a spreadsheet with Indian PIN codes mapped to the city/town/district and state.
You can use the PIN code listing here - http://pincodes.bharatiyamobile.com/ or another one which is accurate.
Format of spreadsheet should be.
Column Column Column
Row PIN Code >> City/Town/District >> State
City/Town/District can be one or all values but has to be in one cell with multiple values separated by comma Eg - Bhiwandi,Thane
Data should be able to be imported into a Database for Location auto-complete function based on pincode.
