Excel data needs to be updated in existing SQL table

Question

I am exporting data from excel and show it in gridview and when I click submit, it needs to be updated in existing table.

 

Below is my excel data

 

S.No. RequestID Subdivision No Parcel No CUID Status Remarks

1        5                 42                    55            55       Open  Pending

 

I have successfully exported and show it in Gridview. Now I want to update the same in the existing table(Tablename:ParcelInf).

 

Below is my table detail

 

Table ParcelInf(

[RequestID] [int] IDENTITY(1,1) NOT NULL,

FormattedRequestID AS ('CUID' + RIGHT('00' + CAST(RequestID AS VARCHAR(10)),10)),

[SubdivisionNo] [nvarchar](20) NOT NULL,

[ParcelNo] [nvarchar](20) NOT NULL,

[Region] [nvarchar](20) NULL,

[City] [nvarchar](20) NULL,

[Zone] [nvarchar](20) NOT NULL,

[CoordinateSystem] [nvarchar](20) NOT NULL,

[CUID] [nvarchar](20) NULL,

[Status] [nvarchar](20) NULL,

[Remarks] [nvarchar](20) NULL,

[UpdateDate] [date] NULL,

[RequestedBy] [nvarchar] (20) NULL,

FOREIGN KEY (RequestID) REFERENCES RequestInf (RequestID)

 

Could you please help me on this.
