Extract Text from Comments in Excel in Python
You can get the text of comments using the ExcelCommentObject.Text property. The detailed steps are as follows.
- Create an object of the Workbook class.
- Load an Excel file using Workbook.LoadFromFile() method.
- Create a list to store the extracted comment text.
- Get the comments in the worksheet using Worksheet.Comments property.
- Traverse through the comments.
- Get the text of each comment using ExcelCommentObject.Text property and append it to the list.
- Save the content of the list to a text file.
- Python
from spire.xls import *
from spire.xls.common import *
# Create a Workbook object
workbook = Workbook()
# Load an Excel file
workbook.LoadFromFile("Comments.xlsx")
# Get the first worksheet
worksheet = workbook.Worksheets[0]
# Create a list to store the comment text
comment_text = []
# Get all the comments in the worksheet
comments = worksheet.Comments
# Extract the text from each comment and add it to the list
for i, comment in enumerate(comments, start=1):
comment_text.append(f"Comment {i}:")
text = comment.Text
comment_text.append(text)
comment_text.append("")
# Write the comment text to a file
with open("comments.txt", "w", encoding="utf-8") as file:
file.write("\n".join(comment_text))
Extract Images from Comments in Excel in Python
To get the images embedded in Excel comments, you can use the ExcelCommentObject.Fill.Picture property. The detailed steps are as follows.
- Create an object of the Workbook class.
- Load an Excel file using Workbook.LoadFromFile() method.
- Get a specific comment in the worksheet using Worksheet.Comments[index] property.
- Get the embedded image in the comment using ExcelCommentObject.Fill.Picture property.
- Save the image to an image file.
- Python
from spire.xls import *
from spire.xls.common import *
# Create a Workbook object
workbook = Workbook()
# Load an Excel file
workbook.LoadFromFile("ImageComment.xlsx")
# Get the first worksheet
worksheet = workbook.Worksheets[0]
# Get a specific comment in the worksheet
comment = worksheet.Comments[0]
# Extract the image from the comment and save it to an image file
image = comment.Fill.Picture
image.Save("CommentImage/Comment.png")
