Get document info Leave feedback
On this page
With GroupDocs.Parser you can retrieve the following information about a document:
file_typerepresents the document file type (PDF, Word document, Excel spreadsheet, PowerPoint presentation, image etc.)page_countrepresents the number of pages in a documentsizerepresents the document file size in bytes
The following code samples show how to get document information:
from groupdocs.parser import Parser
# Create an instance of Parser class
with Parser("./sample.docx") as parser:
# Get the document info
doc_info = parser.get_document_info()
# Print document information
print(f"File type: {doc_info.file_type.file_format}")
print(f"Page count: {doc_info.page_count}")
print(f"File size: {doc_info.size} bytes")
# Print file extension
print(f"File extension: {doc_info.file_type.extension}")
The following sample file is used in this example: sample.docx
from groupdocs.parser import Parser
# Open the file stream
with open("sample.pdf", "rb") as stream:
# Create an instance of Parser class with the stream
with Parser(stream) as parser:
# Get the document info
doc_info = parser.get_document_info()
# Print document information
print(f"File type: {doc_info.file_type.file_format}")
print(f"Page count: {doc_info.page_count}")
print(f"File size: {doc_info.size} bytes")
The following sample file is used in this example: sample.pdf
It’s useful to check document properties before performing extraction operations:
from groupdocs.parser import Parser
def process_document(file_path):
with Parser(file_path) as parser:
# Get document information
doc_info = parser.get_document_info()
print(f"Processing: {file_path}")
print(f"Type: {doc_info.file_type.file_format}")
print(f"Pages: {doc_info.page_count}")
print(f"Size: {doc_info.size / 1024:.2f} KB")
# Process based on page count
if doc_info.page_count > 0:
print("Document has pages, proceeding with text extraction...")
text_reader = parser.get_text()
if text_reader:
print(text_reader)
else:
print("Document has no pages or page count is not available")
# Process different document types
process_document("sample.pdf")
The following sample file is used in this example: sample.pdf
For multi-page documents, you can also get information about individual pages:
from groupdocs.parser import Parser
with Parser("./sample.docx") as parser:
# Get document info
doc_info = parser.get_document_info()
print(f"Total pages: {doc_info.page_count}")
# Iterate through pages
for page_index in range(doc_info.page_count):
# Extract text from each page
print(f"
--- Page {page_index + 1} ---")
text_reader = parser.get_text(page_index)
if text_reader:
page_text = text_reader
print(f"Characters: {len(page_text)}")
The following sample file is used in this example: sample.docx
If a document format doesn’t support certain features, the API returns appropriate values:
from groupdocs.parser import Parser
try:
with Parser("./unknown.format") as parser:
doc_info = parser.get_document_info()
if doc_info:
print(f"File type: {doc_info.file_type.file_format}")
# Some formats may not have page count
if doc_info.page_count == 0:
print("Page count is not available for this format")
else:
print("Could not retrieve document information")
except Exception as e:
print(f"Error: {e}")
