You can directly extract and transform data to various formats. Available options are:

  • JSON (Default option; Default API output)
  • CSV
  • SQL (compatible with Umami Analytics PostgreSQL backend)
ga-extractor migrate --format=CSV
# Report written to /home/user/.config/ga-extractor/02c2db1a-1ff0-47af-bad3-9c8bc51c1d13_extract.csv

head /home/user/.config/ga-extractor/02c2db1a-1ff0-47af-bad3-9c8bc51c1d13_extract.csv
# path,browser,os,device,screen,language,country,referral_path,count,date
# /,Chrome,Android,mobile,1370x1370,zh-cn,China,(direct),1,2022-03-18
# /,Chrome,Android,mobile,340x620,en-gb,United Kingdom,,1,2022-03-18

ga-extractor migrate --format=UMAMI
# Report written to /home/user/.config/ga-extractor/cee9e1d0-3b87-4052-a295-1b7224c5ba78_extract.sql

# IMPORTANT: Verify the data and check test database before inserting into production instance 
# To insert into DB (This should be run against clean database):
cat cee9e1d0-3b87-4052-a295-1b7224c5ba78_extract.sql | psql -Upostgres -a some-db

You can verify the data is correct in Umami web console and GA web console:

Note: Some data in GA and Umami web console might be little off, because GA displays many metrics based on sessions (e.g. Sessions by device), but data is extracted/migrated based on page views. You can however confirm that percentage breakdown of browser or OS usage does match.
