AI remarks: in this in cgst and sgst have two sub column their percentage and their value read it name cgst value and cgst % so for sgst,so now you have to make it perfect and proper,please donot mesh data becase if there blank keep the blank in proper manner,Strict column-position rule: If any column in the uploaded/imported data is blank, keep that column blank. Never shift data from the next column into the blank column. Data must always remain mapped to its original column position.This is a critical data-integrity requirement. Column position must be preserved exactly as provided in the source file. Blank values must remain blank/null, and subsequent columns must never be shifted left to fill the blank. This issue occurs regularly with fields such as Old MRP, which may legitimately be blank while Revised MRP contains a value. The system must handle this correctly in every case. Rule: Blank column = Blank value Next column = Next column Never shift, infer, or auto-fill values based on adjacent columns.
