What is the best way to save the contents of a StringGrid?

What is the best way to save the contents of the StringGrid every time the program is closed?

You can save the data as a text file, ini/config file, xml, database or (Windows) registry.

What is the best depends on the complexity and size of the data, and what method is most convenient to you.

And this is my demo showing how to load data from a dbf file to a string grid:

why not to use default ability? these methods:
    procedure LoadFromCSVStream(AStream: TStream; ADelimiter: Char=',';
      UseTitles: boolean=true; FromLine: Integer=0; SkipEmptyLines: Boolean=true); virtual;
    procedure LoadFromCSVFile(AFilename: string; ADelimiter: Char=',';
      UseTitles: boolean=true; FromLine: Integer=0; SkipEmptyLines: Boolean=true);
    procedure SaveToCSVStream(AStream: TStream; ADelimiter: Char=',';
      WriteTitles: boolean=true; VisibleColumnsOnly: boolean=false);
    procedure SaveToCSVFile(AFileName: string; ADelimiter: Char=',';
      WriteTitles: boolean=true; VisibleColumnsOnly: boolean=false);

Yes, I forgot about it.

The CSV-related procedures save/load only the cell content. If you also want to handle grid layout (col count, row count, colwidths, ...), focused cell, colors (when working with columns) etc you should use SaveToFile and LoadFromFile. There is a chapter in the grids wiki about it: https://wiki.lazarus.freepascal.org/Grids_Reference_Page#Save_and_Retrieve_Grid_Content
