Pretty Printer for T-SQL?

Question

I\'m looking for a good T-SQL Pretty Printer so that all the code looks consistent between developers in our project. Preferably a free/open source one, but paid for isn\'t out

I had the same issue but I was looking for a command line tool. I have finally coded a Python script based on sqlparse that is a Python package mature (10+ years), still very active and aiming to parse and format SQL statements.

In post here my tiny Python script pretty_print_sql.py in case other users would be interested:

import argparse
import sqlparse

# Parse command line arguments
parser = argparse.ArgumentParser(prog="pretty_print_sql")
parser.add_argument("file", type=argparse.FileType("r"), nargs="+")
args = parser.parse_args()

# Pretty print input files
for file in args.file:
    print(sqlparse.format(file.read(), reindent=True, keyword_case='upper'))

To use it:

pretty_print_sql.py input.sql > pretty-output.sql

To install sqlparse using pip for personal usage:

python3 -m pip install sqlparse --user --upgrade

To install sqlparse using pipenv (within a project):

python3 -m pipenv install sqlparse
