Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited support for complex data transformations

   CSVKit is primarily designed for basic CSV operations and lacks advanced data transformation capabilities found in more comprehensive ETL tools.

2. 02

   Performance issues with very large datasets

   Processing multi-gigabyte CSV files can be slow due to memory limitations of the Python environment, leading to potential out-of-memory errors or long processing times.

3. 03

   Poor documentation for advanced use cases

   The official documentation focuses on basic usage and lacks detailed examples and explanations for more complex operations, making it difficult for users to leverage CSVKit's full potential without extensive trial and error.

4. 04

   Limited support for non-CSV data formats

   While CSVKit excels at handling CSV files, its ability to convert from or to other data formats like JSON, XML, or databases is limited compared to more versatile data manipulation tools.

What it does well

• Converts various data formats to CSV

• Manipulates and processes CSV files efficiently
