CSV URL Parser is an Agent Skill for documents published in the majiayu000/claude-skill-registry repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Parse URLs in CSV files and extract query parameters as new columns. Use when working with CSV files containing URLs that need parameter extraction and analysis.

CSV URL Parser

This skill extracts query parameters from URLs in CSV files and adds them as new columns.

Instructions

  1. Identify CSV files: Look for CSV files in the current directory or specified path
  2. Analyze URL column: Find the column containing URLs (looks for 'url' or 'URL' headers)
  3. Extract parameters: Parse all query parameters from URLs
  4. Create new columns: Add parameter names as new column headers
  5. Process data: Fill new columns with parameter values (multiple values joined with '|')
  6. Save results: Update the CSV file with new columns

Implementation

The skill uses Ruby to process CSV files. Run the processing script:

ruby scripts/process_csv.rb [file1.csv file2.csv ...]

If no files are specified, it processes all CSV files in the current directory.

The script will:

  • Read CSV files with headers
  • Extract query parameters from URLs using URI parsing
  • Handle multiple values for the same parameter (joined with '|')
  • Preserve original data while adding new parameter columns
  • Handle malformed URLs gracefully

For detailed examples, see EXAMPLES.md.

Usage Examples

Process all CSV files in current directory:

Parse URLs in my CSV files

Process specific CSV file:

Extract URL parameters from data.csv

Analyze URL parameters:

Show me what parameters are in the URLs from this CSV

Requirements

  • Ruby with standard libraries (CSV, URI, CGI)
  • CSV files must have headers
  • URL column should be named 'url' or 'URL'

Output

  • Original CSV file updated with new parameter columns
  • Multiple parameter values separated by '|'
  • Preserves all original data
  • Handles empty/missing parameters gracefully
