Auto-highlight keywords in documents

To auto-highlight keywords in documents, you can use several methods depending on the environment you’re working in. Below are different approaches for various platforms:

1. In Microsoft Word

Use “Find and Replace” with Highlighting:

1. Press Ctrl + H to open Find and Replace.

2. In Find what, type your keyword.

3. Click More >>, then click Format > Highlight.

4. Leave Replace with the same as Find what, then click Replace All.

Repeat this for each keyword.

2. Using Python (for DOCX, PDF, or TXT documents)

Example for .docx using python-docx:

python
CopyEdit
from docx import Document
from docx.enum.text import WD_COLOR_INDEX

keywords = ['AI', 'automation', 'keyword']
doc = Document("yourfile.docx")

for para in doc.paragraphs:
    for keyword in keywords:
        if keyword in para.text:
            for run in para.runs:
                if keyword in run.text:
                    run.font.highlight_color = WD_COLOR_INDEX.YELLOW

doc.save("highlighted.docx")

Example for .txt or basic content display:

python
CopyEdit
keywords = ['AI', 'automation', 'keyword']
with open('document.txt', 'r') as file:
    content = file.read()

for word in keywords:
    content = content.replace(word, f'33[43m{word}33[0m')  # Yellow background in terminal

print(content)

3. In Google Docs (Manually or with Script)

Manual:

Use the search bar (Ctrl + F) to find each keyword, then apply highlight manually.

Using Apps Script:

javascript
CopyEdit
function highlightKeywords() {
  var doc = DocumentApp.getActiveDocument();
  var body = doc.getBody();
  var keywords = ['AI', 'automation', 'keyword'];

  keywords.forEach(function(keyword) {
    var searchResult = null;
    while (searchResult = body.findText(keyword, searchResult)) {
      var text = searchResult.getElement().asText();
      var start = searchResult.getStartOffset();
      var end = searchResult.getEndOffsetInclusive();
      text.setBackgroundColor(start, end, '#FFFF00'); // Yellow
    }
  });
}

Run this from the Google Apps Script editor in your document.

4. Online Tools

There are online tools like:

• Online-Utility.org Keyword Highlighter

• SEO-ToolKit Keyword Density Analyzer

They auto-highlight keywords in pasted content or uploaded documents.

5. With JavaScript (For Webpages or HTML)

javascript
CopyEdit
function highlightText(keyword) {
  const regex = new RegExp(`(${keyword})`, 'gi');
  document.body.innerHTML = document.body.innerHTML.replace(regex, '<mark>$1</mark>');
}

['AI', 'automation', 'keyword'].forEach(highlightText);

You can run this in the browser console or inject it into a webpage.

Choose your method based on your environment: Word for document editing, Python for automated batch processing, Google Docs for cloud collaboration, or JavaScript for web-based content.
