gsdownload

Download Google sheets as CSVs using a service account.

Process overview

1. Create a Google service account
2. Share your spreadsheet with that account
3. Provide credentials from that account to gsdownload along with a sheet ID and it will download each worksheet as a CSV file to a location you specify

Be careful not to leak your private key. Provide it as an environment variable/ secret and don't commit it to your repository

This mainly developed for use in a CI context so...

CI usage

To use gsdownload in a CI context (like Github actions for example) you need to

1. set GOOGLE_CLIENT_EMAIL and GOOGLE_PRIVATE_KEY as environment variables / secrets for github actions you can do this in the repo Settings->Secrets->Actions i.e. https://github.com/<username/orgname>/<reponame>/settings/secrets/actions
2. make sure your task runner can install & run node scripts and in your CI workflow globally install gsdownload npm i -g @tomgp/gsdownload
3. in your CI workflow add the command getsheet <sheetID> <output_directory> and the worksheet CSVs should hopefully appear in output_directory

otherwise, to use it in anothe Node script...

const  { getSheet } = require('./index.js');
getSheet( <Spreadsheet_ID>, <Google_service_account_email_address>, <Service_account_private_key>, <Output_directory>);
