How to Remove All Blank Lines from a Google Doc Using Google Apps Script
Google Docs is a versatile tool, but sometimes it requires a bit of customization to fit your needs perfectly. If you’ve ever faced the tedious task of removing all blank lines from a lengthy document, you’re in luck. With Google Apps Script, you can automate this task. In this blog post, I will guide you through creating a Google Apps Script to remove all blank lines from a Google Doc.
Step-by-Step Guide
Step 1: Open the Google Apps Script Editor
- Open your Google Doc.
- Click on
Extensions
in the menu bar. - Select
Apps Script
from the dropdown menu.
This will open the Google Apps Script editor in a new tab.
Step 2: Write the Script
Copy and paste the following script into the editor:
function removeBlankLines() {
var doc = DocumentApp.getActiveDocument();
var body = doc.getBody();
var paragraphs = body.getParagraphs();
for (var i = paragraphs.length - 1; i >= 0; i--) {
var paragraph = paragraphs[i];
if (paragraph.getText().trim() === '') {
body.removeChild(paragraph);
}
}
Logger.log('All blank lines have been removed.');
}
Explanation of the Script:
DocumentApp.getActiveDocument()
: Gets the active Google Doc.body.getParagraphs()
: Retrieves all paragraphs in the document.- The
for
loop iterates through each paragraph from the end to the beginning. paragraph.getText().trim() === ''
: Checks if a paragraph is blank.body.removeChild(paragraph)
: Removes the blank paragraph.
Step 3: Save and Run the Script
- Click the disk icon or press
Ctrl + S
to save your script. Give it a name like “RemoveBlankLines”. - Click the play button (triangle icon) to run the script.
Step 4: Authorize the Script
The first time you run the script, you will need to authorize it:
- A dialog will appear saying “Authorization required”. Click
Review Permissions
. - Choose your Google account.
- Click
Allow
to grant the necessary permissions.
Step 5: Check Your Document
Return to your Google Doc and verify that all blank lines have been removed. If there are still blank lines, re-run the script to ensure it catches all instances.
Customizing the Script
If you want to customize this script further, here are a few ideas:
- Target Specific Sections: Modify the script to only remove blank lines from certain sections of your document.
- Add User Prompts: Use
ui.prompt()
to ask the user for confirmation before removing lines. - Log Removed Lines: Keep a log of all removed lines for audit purposes.
Conclusion
Automating tasks in Google Docs using Google Apps Script can save you a lot of time and effort. This script to remove blank lines is just a starting point. With a bit of creativity, you can tailor it to fit your specific needs.
