CSV Cleaner
Quickly clean your CSV data by deduplicating, sorting, or filtering rows. Perfect for preparing datasets for analysis or import.
Deduplicate Rows
Remove rows that are duplicates based on the entire row or a specific column's value.
The CSV Cleaner is a powerful browser-based utility for tidying up your CSV (Comma-Separated Values) files. Raw data often contains errors, inconsistencies, or redundant entries that can skew analysis or cause import failures. This tool provides essential cleaning functions, starting with deduplication, to help you quickly normalize your dataset. All processing is done securely on your local machine, ensuring your data's privacy.
How to Use the Tool
- Input Data: Paste your CSV content into the input box on the left.
- Choose a Cleaning Action: Start with deduplication. Specify which column should be checked for unique values. Enter `1` for the first column, `2` for the second, and so on. Enter `0` to check if the entire row is a duplicate.
- Process: Click the corresponding button (e.g., "Deduplicate"). The cleaned data will appear on the right.
- Copy or Download: You can copy the result to your clipboard or download it as a new `.csv` file.
