Command Line CSV Processing Tutorial: Merge, Clean, and Convert from Terminal

Command Line CSV Processing

When you have dozens of CSV files to merge, clean, and convert, doing it manually in Excel is painful.

Here is how to do it from the terminal.

Merge Multiple CSV Files

toolkit csv merge sales_*.csv -o merged.csv

Clean Duplicates

toolkit csv clean merged.csv --deduplicate -o clean.csv

Convert to JSON

toolkit json convert data.csv -o data.json

Complete Pipeline

Create pipeline.json:

{
  "name": "Monthly Report",
  "steps": [
    { "tool": "csv", "args": ["merge", "sales_*.csv", "-o", "merged.csv"] },
    { "tool": "csv", "args": ["clean", "merged.csv", "--deduplicate", "-o", "clean.csv"] },
    { "tool": "json", "args": ["convert", "clean.csv", "-o", "report.json"] }
  ]
}

Run: toolkit pipeline pipeline.json
