Every day, the volume of data being generated grows exponentially. Journalists, analysts, and data visualizers eagerly transform this data into compelling stories and insightful visualizations. However, before diving into data analysis, one critical question stands out: “Is my data reliable?” Whether it’s inaccuracies, duplicates, or missing values, the integrity of your dataset is paramount. Fear not! Dataproofer comes to the rescue by automating the tedious process of checking datasets for errors and inconsistencies. This guide will help you get started with Dataproofer on your desktop and command line.

Getting Started (Desktop)

To begin your journey with Dataproofer on desktop, follow these simple steps:

1. Download a .zip of the latest release from the Dataproofer releases page.
2. Drag the app into your Applications folder.
3. Select your dataset, which can be a CSV on your computer or a Google Sheet that you’ve published to the web.
4. After selecting your dataset, you can customize which suites and tests to run by toggling them on or off.
5. Once you’re ready, proof your data, get your results, and gain confidence in your dataset!

Getting Started (Command Line)

If you are more comfortable using the command line, here’s how you can get started:

sh
npm install -g dataproofer
sh
dataproofer --help

This will install Dataproofer globally and display its help options including versions and suites available for testing.

Command Options

Here’s a glimpse of the command options you can use:

• -h, --help : output usage information
• -V, --version : output the version number
• -o, --out file : specify a file to output results
• -c, --core : run tests from the core suite
• -i, --info : run tests from the info suite
• -a, --stats : run tests from the statistical suite
• -g, --geo : run tests from the geographic suite

Understanding the Code Analogy

Think of data verification with Dataproofer as assembling a puzzle. Each piece of data is a puzzle piece that must fit perfectly with others to create a coherent image. Just like you wouldn’t want a few puzzle pieces out of shape or from a different puzzle, you don’t want any inaccuracies in your dataset. Dataproofer diligently checks each piece (or data point) to ensure it correctly aligns with the bigger picture you’re trying to achieve — be it a report or a visualization.

Troubleshooting

If you encounter any issues while running your tests or using Dataproofer, here are some troubleshooting tips:

• These tests are executed in a try-catch loop, so consider temporarily removing the try-catch while iterating on a test.
• Make extensive use of console.log statements and the Chrome debugger to diagnose issues.
• If you find a bug, we encourage you to report it on the issue tracker.
