Question

I need a help to import csv file

Asked by: hidrau

Hello guys,

I have a CSV file that must be imported and I need to get two information from it.
Date and Order

I attached the file to be used as example.

In CSV file there is a line named Header, in this line I need to get the date that is the second column

In the second line named " detail " I need to get the order

Then, the values from my example:
Date                                        order
20091023T00:00:00-02:00     1314526-0

the last line for each order named "Summary"

After each "Summary" a new order comes

Thanks

Here is the decoding part of your CSV file. You just have to implement the treatments, with this fields are already split and accessible by index in L:TStringList

Var
 F,L:TStringList;
 H:String;
 S:String;
 i,p:Integer;
// treatment specific vars
 DateStr:String; Date before conversion
 Order:String; 
begin
 F:=TStringList.Create;
 F.LoadFromFile('CSVDocument.csv');
 L:=TStringList.Create;
 for i=0 to F.Count-1 do
  begin
   S:=F[i];
   P:=Pos(':',S);
   H:=Trim(LeftStr(S,P-1));
   L.CommaText:=Copy(S,P+1,Length(S));
//== At this point, you have for each line 
// H : the Header value of the line ( Header, Detail, Summary )
// L : the list of all fields of the line 
// where L.Count is the number of fields
// L[0] the first field etc..
//== You just have to implement your specific tasks
   if H='Header' Then 
    DateStr:=L[1]; // 20091023T00:00:00-02:00 is on the second column
   if H='Detail' Then 
    Order:=L[1];   
  end;
 L.Free;
 F.Free;
end;
