SQLite to CSV
Its easy to export your current SQLite data into Excel or CSV format.
This can be achieved by simple code, which includes csv text file format, which we need to write through code.
CSV format works on the basis of comma and new line.
The below code includes.
1. File creation
2. Writing data to file
3. Fetching data from SQLite & writing in csv format.
You can modify your format however you want, keeping in your mind about commas.
Call this method & pass your file & directory path.
