The CSV Lint plugin is an exceptional tool for validating and formatting CSV (comma-separated values) and fixed width data files within Notepad++. In this article, we will explore how to install, configure, and effectively use the CSV Lint plugin to ensure your data is error-free and well formatted.

Installing CSV Lint in Notepad++

To get started with CSV Lint, here’s how to install it:

1. Make sure you have [Notepad++](http://notepad-plus-plus.org) installed on your PC.
2. Open Notepad++ and navigate to Plugins in the top menu, then select Plugins Admin…
3. In the Available tab, search for csv lint.
4. Check the box next to CSV Lint and click the Install button.
5. Click Yes to quit Notepad++ and continue the operation.
6. When prompted, click Yes on the Windows notification to allow changes.

Note that the plugin is available via the Plugins Admin menu starting from Notepad++ version 8.1.9.1. If you are using an older version or want to install the plugin manually, you can follow these steps:

• Go to the releases page.
• Download the latest release and unzip the appropriate version (32bit or 64bit) to the appropriate folder in your Notepad++ installation.
• Restart Notepad++.

How to Use CSV Lint

Once installed, you can use CSV Lint to analyze and validate your datasets:

1. Open your dataset in [Notepad++](http://notepad-plus-plus.org).
2. Access the CSV Lint window from the plugins menu or toolbar.
3. Click Detect columns to automatically detect the data format.
4. You can choose to manually adjust the metadata if necessary.
5. Click Validate data to check for any errors in your data.

If your data passes validation, you have the option to click Reformat data for formatting options or select Convert to SQL to generate an SQL insert script.

Understanding Schema.ini

The CSV Lint plugin utilizes the standard schema.ini format for metadata. When opening a CSV file, the plugin checks for a schema.ini file in the same folder, allowing manual adjustments for precise configuration of how data is interpreted.

For example, a schema.ini may look like this:

[mydata.csv]
Format=TabDelimited
DateTimeFormat=dd-mm-yyyy
DecimalSymbol=.
NumberDigits=2
Col1=OrderId Integer Width 8
Col2=Price Float Width 7
Col3=PartName Text Width 50
Col4=OrderDate DateTime Width 10

Troubleshooting Common Issues

If you encounter problems while using CSV Lint, here are some common troubleshooting tips:

• If the validation results seem incorrect after editing, try saving the data file or refreshing the metadata before revalidation.
• For datetime format issues, particularly with ambiguous formats like ‘05062024’, make manual adjustments before validating.
• When enabling syntax highlighting, column colors might not update immediately. Click into the text file or switch to another tab and back to refresh the colors.
