Exporting Data to CSV Format Using Google Apps Script
- To export data to CSV format using Google Apps Script, activate the Advanced Drive Service and the Drive API. This ensures the script can interact with Google Drive to save files.
- Use the <code>convertRangeToCsvFile_</code> function to create a CSV file from a Google Sheet. Fetch the data from the sheet using <code>getDataRange()</code> and <code>getDisplayValues()</code>. These methods retrieve and format the displayed values from the sheet into CSV format.
- Loop through the fetched data to build a CSV string. Concatenate the string to join each row, and use the <code>join</code> method to join each column in a row, adding a carriage return at the end of each row. Return the formatted CSV string.
- Generate the CSV file using Google Apps Script by fetching the URL <code>"https://docs.google.com/spreadsheets/d/"+ ssID+"/export?gid='+sheetNameId +'&format=csv"</code> with the method <code>"GET"</code>. Set the header "Authorization" to "Bearer " + ScriptApp.getOAuthToken(). Use the Drive API to create and save the CSV file in Google Drive.
- The CSV file can be saved in a specific folder by providing the folder ID. It can also be saved in "My Drive" or a shared drive. Apply a timestamp to the file name for better organization and tracking.
- Set up a timer trigger to automate the script and run it daily. This ensures that the CSV file is updated and saved regularly without manual intervention.
- To illustrate, the function <code>convertRangeToCsvFile_</code> takes sheet and rowsPerFile as parameters. It retrieves the data range using <code>sheet.getDataRange()</code>, builds the CSV string by looping through the data, and returns the CSV string for saving to Google Drive.

How to Export Your Data to CSV Format Using Google Apps Script
Overview
Exporting data to CSV format using Google Apps Script is a straightforward process. This guide will provide step-by-step instructions on how to achieve this efficiently, leveraging various Google Apps Script features and the Google Drive API.
Fetching CSV Data
To fetch CSV data in Google Apps Script, use the UrlFetchApp.fetch() method. This method allows you to retrieve the CSV file from a specified URL.
The request method should be set to GET, and the authorization header must be "Bearer " + ScriptApp.getOAuthToken() to authenticate the request properly.
Obtaining Spreadsheet and Sheet IDs
First, get the spreadsheet ID using SpreadsheetApp.getActiveSpreadsheet().getId(). For a specific sheet, use the getSheetByName("Sheet1") method.
Then, obtain the sheet ID with sheet.getSheetId().toString(). Construct the CSV URL using ssID+"/export?gid='+sheetNameId +'&format=csv".
Fetching and Inserting CSV into Google Drive
Use UrlFetchApp.fetch(url, requestData) to fetch the CSV file from the constructed URL. To save the CSV file into Google Drive, use the Drive.Files.insert(resource, result) method.
Ensure you set the parents property accordingly to save the CSV in a specific folder. Use MimeType.CSV to make the file recognizable by Google Drive.
Additional Tips
You can also use the Google Drive API to import and export Apps Script source code, making it possible to manage your code from your local machine.
Remember, the Google Drive API uses GET to download files and PUT/POST to upload files. Container-bound scripts and non-source code resources like project properties or logs cannot be imported or exported through this API.
Conclusion
By following these steps, you can efficiently export your data to CSV format using Google Apps Script. This approach simplifies data management and enhances your workflow, leveraging the capabilities of Google Drive and Google Apps Script.
