This is the wiki page for mapping out the Data Quality scripts

Goals

• Compare two Excel files to determine if data was added, changed, or deleted
• Determine if an Excel file follows its predefined format
• Check if numbers are in line with older records

What Things Do and How to Run

NOTES: Be sure to change the directory to where the script is located using cd

Use tab for auto-completing words to reduce the amount of typing

cd Documents/GitHub/Data-Quality-Checker/scripts

Excel Diff

• Credit to Matthew Kudija for the Source Code
• Highlights differences between two Excel files
• Exports file with highlighted differences

Running Excel Diff through Terminal: python diff.py old.xlsx new.xlsx

python diff.py ../files/monthly_production_05-2019 ../files/monthly_production_06-2019.xlsx

Format Checker

• A Python script that accepts an Excel file
• Creates formats based on sample Excel files
• Checks given Excel file for:
  • New or Missing Field Names
  • Unexpected or missing Field Entries
  • Unexpected Units of measurement or New items

Setup needs to be run only once per format, run again if new stuff is added

Running Setup through Terminal: python formatcheck.py setup filename.xlsx

python formatcheck.py setup '../files/monthly_revenue_05-2019 (1).xlsx'

Running Format Check through Terminal: python formatcheck.py filename.xlsx

python formatcheck.py ../files/monthly_revenue_05-2019.xlsx

Highlighter

• Similar to Format Checker
• Exports an Excel File highlighting anomalies
• Can use same config files as formatcheck.py

Running Highlighter through Terminal: python highlighter.py "filename.xlsx"
