jeez if you were going MySQL to MySQL it would be easy, changing to different types usage is more difficult. There are free and commercial tools available online for conversion. For instance
https://www.altova.com/database-conversion
or
https://www.rebasedata.com/convert-mysql-to-sqlite-online

Via CLI

Using CURL
Replace file.sql with the path to the MySQL .SQL file you want to convert.
The file output.zip will contain a .SQLITE file with your data or the error message if something went wrong.

curl -F 'files[]=@file.sql' 'https://www.rebasedata.com/api/v1/convert?outputFormat=sqlite&errorResponse=zip' -o output.zip

Make backups first!!!!
