You can right-click on the snippet collection you are interested in and choose "Export".
Then this python3 script should print the details out (change "snippetExportFile" with your exported filename).
#!/usr/bin/env python3
from zipfile import ZipFile
import os
import json
snippetExportFile = '/Users/kpw/Desktop/kpw.alfredsnippets'
with ZipFile(snippetExportFile, 'r') as zip:
files = zip.filelist
for zipfile in files:
if zipfile.filename.endswith(".json"):
with zip.open(zipfile.filename) as myfile:
snippetFileJson = myfile.read()
alfredDict = json.loads(snippetFileJson.decode('utf-8'))
snippetDict = alfredDict["alfredsnippet"]
print(f'Name:\t\t{snippetDict["name"]}')
print(f'Keyword:\t{snippetDict["keyword"]}')
snippetText = snippetDict["snippet"].replace("\n", "\\n")
print(f'Snippet:\t{snippetText}')
print("-" * 80)
