✦Use Claude Cowork

Automate Tasks

Process files in batch, set up workflows, and eliminate repetitive work.

What's possible

  • Batch-rename and reorganize files based on rules
  • Extract specific data from multiple PDFs or documents
  • Convert files between formats (CSV to JSON, Markdown to HTML, etc.)
  • Generate standardized reports from raw data
  • Process form responses and compile results
  • Clean and transform data across multiple spreadsheets

Getting started

  1. 1

    Identify the repetitive task

    Think about what you do repeatedly — renaming files, reformatting data, extracting information from documents, converting formats.

  2. 2

    Describe the process to Claude

    Explain what you do step by step. Be specific: what's the input, what do you do to it, what's the expected output?

  3. 3

    Start with a small batch

    Give Claude a few files or records to process first. Verify the output is correct before scaling up.

  4. 4

    Scale up

    Once the process is validated, point Claude at the full batch. Cowork can work through large sets of files in the background.

  5. 5

    Review and save

    Check the results, then save the process description so you can repeat it next time.

Example prompts

File processing

“I have 50 PDF invoices in my Downloads folder. Extract the vendor name, date, and total amount from each one and put it all in a spreadsheet.”

Data transformation

“Convert all the CSV files in this folder to a single Excel workbook, with each CSV as a separate sheet. Clean up any encoding issues.”

Content generation

“Here's a spreadsheet of 30 products with names, descriptions, and prices. Generate a formatted product catalog page for each one.”

Email processing

“I've exported my inbox as .eml files. Go through them and create a summary of all action items directed at me, organized by sender.”

Tips

  • Always test with a small sample first. Process 3-5 files, verify the output, then run the full batch.
  • Be explicit about edge cases — what should Claude do if a file is missing data or in an unexpected format?
  • Save your prompts. The next time you need to run the same process, you can paste the prompt and point at new files.
  • For complex multi-step workflows, describe the full pipeline upfront so Claude can plan the most efficient approach.
