how to get google spreadsheet by api
IN SUMMARY
To get data from a Google Spreadsheet using an API, you need to follow a few steps: enable the Google Sheets API, create a project and credentials, authenticate your application, and then use the API to retrieve the spreadsheet data.
Enable the Google Sheets API
Visit the Google Cloud Console (console.cloud.google.com) and log in with your Google account. This account should have access to the spreadsheet you want to retrieve data from.
If you don't have a project yet, create a new one by clicking on the project dropdown at the top of the console and selecting 'New Project'. Otherwise, select an existing project from the list.
In the console, navigate to the 'APIs & Services' section, then click on 'Library'. Search for 'Google Sheets API' and enable it for your project.
Create Credentials
In the 'APIs & Services' section, go to 'Credentials' and click on 'Create Credentials'. Select 'Service Account' and follow the prompts to create a new service account with the appropriate permissions to access the spreadsheet.
After creating the service account, you'll be prompted to download a JSON key file. This file contains the credentials you'll need to authenticate your application with the Google Sheets API.
Open the spreadsheet you want to access and share it with the email address of the service account you just created. Make sure to grant the appropriate permissions (e.g., 'Editor' or 'Reader').
Authenticate and Use the API
Depending on your programming language, you'll need to install the appropriate Google API Client Library. For example, in Python, you can use the 'google-auth' and 'google-api-python-client' libraries.
Use the JSON key file you downloaded earlier to authenticate your application with the Google Sheets API. The specific code will depend on the programming language and library you're using.
Once authenticated, you can use the Google Sheets API to retrieve data from the spreadsheet. The API provides methods to read and write data, as well as perform other operations like formatting cells or adding sheets.
