Introduction

Converting PDF files to DOCX format is a common task in document management and workflow automation. However, when using the LibreOffice unoconv tool, errors can occur, causing frustration and delays. In this article, we will explore the common issues and solutions for PDF to DOCX conversion errors using the unoconv tool.

Understanding the Error Message

The error message unoconvert error: exit status 1 indicates that the unoconv tool has encountered an error while converting the PDF file to DOCX format. This error can occur due to various reasons, including:

  • Invalid input file: The PDF file may be corrupted or invalid, causing the conversion process to fail.
  • Incorrect conversion options: The conversion options specified in the opts[] parameter may be incorrect or incompatible with the PDF file.
  • LibreOffice configuration issues: The LibreOffice configuration may be incorrect or incomplete, leading to conversion errors.

Analyzing the Log File

The log file provides valuable information about the conversion process, including any errors that occur. By analyzing the log file, we can identify the root cause of the issue and take corrective action.

Docker Image Version

The Docker image version used in this example is libreofficedocker/libreoffice-unoserver:3.19. This version may have known issues or bugs that contribute to the conversion errors.

Log File Analysis

The log file contains the following relevant information:

2025-03-11 13:40:08 unoserver-rest-api 2025/03/11 05:40:08 unoconvert error: exit status 1
2025-03-11 14:10:15 unoserver-rest-api 2025/03/11 06:10:15 unoconvert error: exit status 1
2025-03-11 14:11:03 unoserver-rest-api 2025/03/11 06:11:03 unoconvert error: exit status 1

The repeated occurrence of the unoconvert error: exit status 1 message indicates that the issue is likely related to the conversion process itself.

curl Command Analysis

The curl command used to initiate the conversion process is:

curl --location 'http://127.0.0.1:2004/request' \
--form 'convert-to="docx"' \
--form 'file=@"/Users/dev/Desktop/zgty.pdf"' \
--form 'opts[]=="--infilter="writer_pdf_import"'

The opts[] parameter specifies the conversion options, including the --infilter option, which is set to writer_pdf_import. This option is used to specify the import filter for the PDF file.

Troubleshooting Steps

To troubleshoot the issue, follow these steps:

  1. Verify the input file: Ensure that the PDF file is valid and not corrupted.
  2. Check the conversion options: Verify that the conversion options specified in the opts[] parameter are correct and compatible with the PDF file.
  3. Update the LibreOffice configuration: Ensure that the LibreOffice configuration is correct and complete.
  4. Upgrade the Docker image: Consider upgrading the Docker image to a newer version that may have resolved known issues or bugs.
  5. Monitor the log file: Continuously monitor the log file for any errors or issues that may occur during the conversion process.
