In daily work such as digitizing scanned documents for archiving, converting PDF invoices and tables for data reuse, or batch processing contracts, there is often a need to convert large volumes of PDF files to Word, Excel, JSON, TXT, etc. Traditional methods rely on manual operations or desktop software, which are not only time-consuming but also difficult to integrate into existing workflows.
In the era of AI agents, it’s time to create an automated PDF conversion AI assistant for your team.
This article uses a locally running PDF conversion Skill — ComPDF Conversion CLI — and OpenClaw AI Agent as examples to show you how to quickly build an intelligent assistant that supports batch PDF format conversion.
Install AI Agent
An AI agent is an intelligent entity that can autonomously perceive its environment, make plans, call tools, and execute tasks. Unlike traditional chatbots, an agent has the ability to act — based on the user’s goal, it can decide which tools to call, in what order, and finally return the result.
Steps to Install OpenClaw AI Agent
You can choose any AI agent to install and use. Run the following commands to install the OpenClaw Agent. For detailed installation steps, please refer to the article How to Install OpenClaw.
For Terminal on Mac/Linux:
curl -fsSL https://openclaw.ai/install.sh | bash
For PowerShell or WSL2 terminal on Windows:
iwr -useb https://openclaw.ai/install.ps1 | iex
Install ComPDF Conversion CLI
ComPDF Conversion CLI is a PDF Conversion Skill that can be invoked by an AI agent and encapsulates the ComPDF Conversion SDK. It runs entirely locally — no need to upload files to the cloud, ensuring data security. ComPDF Conversion CLI supports the following PDF conversion features:
-
PDF to Word (preserves formatting and layout, 98% accuracy)
-
PDF to Excel (AI table recognition and extraction)
-
PDF to Image (supports JPG, PNG, etc.)
-
PDF to PPT (preserves page layout)
-
PDF to RTF
-
PDF to CSV
-
PDF to JSON
-
PDF to Markdown
In addition to the PDF conversion functions above, ComPDF Conversion CLI also provides image conversion, supporting batch conversion of common image formats (JPG, PNG, BMP, TIFF, etc.). Click here for the full feature list.
For PDF conversion specifically, ComPDF also offers a PDF Toolkit Skill powered by the ComPDF Open API. It supports over 200 file conversions/processings per month. View installation guide and register for a free license.
Steps to Install ComPDF Conversion CLI
Simply send the following command to your AI agent, and the Skill will be automatically installed.
openclaw skills install compdf-conversion-cli
After installation, ComPDF Conversion CLI comes with a license that includes 200 free conversions, allowing you to start experiencing it immediately.
If you have higher document conversion needs, you can contact the ComPDF team to purchase an official license. Place the obtained license.xml file into the scripts/ directory, overwriting the existing file, to remove conversion limits.
Start Batch PDF Conversion
After completing the above installations, your AI agent is now equipped with batch PDF conversion capabilities. Next, let’s look at a practical example of how to perform batch conversion with just one sentence.
Example instruction: Convert all PDF files in the local folder ~/Downloads/invoices to Excel format and save them to the ~/Documents/converted_excel directory.
Upon receiving the instruction, the AI agent will automatically execute the following steps:
-
Intent recognition: Parse the source path ~/Downloads/invoices, target format excel, and output path ~/Documents/converted_excel.
-
File traversal: Scan the source path to get a list of all .pdf files.
-
Loop conversion: For each file, call the compdf-conversion-cli skill to perform the conversion.
-
Status monitoring: Track conversion progress in real time. If a file is corrupted or a network fluctuation occurs, automatically retry or skip and log the issue.
-
Result summary: After conversion, the agent returns a detailed report including the number of successes/failures and a list of failed files.
-
Output storage: Save the converted Excel files to the output directory.
The entire process requires no human intervention. Even with hundreds of files, the agent can complete the task stably and efficiently.
Use Case Examples
1. Automated Financial Reconciliation:
Finance staff need to convert dozens of bank statement PDFs to Excel each month for reconciliation and reporting. With an AI agent, a single instruction completes batch conversion and automatically archives the results to a designated directory.
2. Batch Contract Document Conversion:
Legal or administrative staff often need to convert contract PDFs into editable Word documents for clause revision. The AI agent can automatically traverse the contract folder, batch convert all PDFs to Word, and save them with original filenames.
3. Product Manual to Image Assets:
Marketing teams need to convert each page of a product manual PDF into images for websites or social media. Using the PDF-to-image feature, the AI agent can generate high-quality JPG/PNG files in one click and automatically name them.
4. Scanned Document Digitization and Data Extraction:
For scanned PDFs, combined with an OCR skill (extendable), the agent can first recognize text and then convert it to Markdown or JSON format for subsequent data analysis and retrieval.
Advantages of ComPDF Conversion CLI Skills
-
Local operation, data security: All conversions are performed locally without uploading files to third-party servers, suitable for sensitive or confidential documents.
-
Zero-code integration: Install and invoke via natural language interaction with the AI agent — no complex scripting or API learning required.
-
Rich format support: Supports over ten output formats including Word, Excel, PPT, images, JSON, and Markdown, covering most office needs.
-
Batch processing capability: The AI agent automatically traverses folders, controls concurrency, and handles retries, easily managing hundreds or thousands of files.
-
Low free trial barrier: 200 free conversions upon installation — zero-cost validation before upgrading to a full license.
-
Easily extensible: As a Skill invoked by the agent, it can be flexibly combined with other skills (e.g., OCR, file renaming, automatic archiving).
Conclusion
By combining the task execution capability of an AI agent with the professional conversion capability of ComPDF Conversion CLI, we have built a fully functional batch PDF conversion AI assistant using just two commands.
Whether you are an enterprise IT manager, administrative staff, or a tech enthusiast looking to improve personal productivity, you can use the method in this article to quickly create a dedicated PDF processing intelligent assistant for yourself or your team.
