The execsql program is available on PyPI.
It can be installed with:
pip install execsql
This will install execsql.py as an executable Python script. Alternatively, you can download execsql.py from the PyPI project page or from the OSDN releases.
In addition to the execsql program itself, additional Python libraries may need to be installed to use execsql with specific types of DBMSs and spreadsheets. The additional libraries that may be needed are listed in the Requirements section.
