Free CSV Tools Online — Clean, Convert and Validate CSV Files

I built a collection of free CSV tools that help clean and convert data quickly.

You can try them here:

https://data-tools-platform.vercel.app/

This website includes multiple tools designed to work directly in the browser, without installing anything.

Some of the tools available:

• CSV Cleaner — remove extra spaces and fix messy CSV files
• CSV to JSON — convert CSV into structured JSON
• JSON to CSV — convert JSON into spreadsheet format
• CSV Validator — check CSV structure and detect errors
• Remove Duplicate Rows — remove repeated data rows
• CSV to Excel — convert CSV files into Excel format
• Excel to CSV — convert Excel files into CSV
• CSV Column Selector — keep only specific columns
• CSV Sorter — sort rows by column
• CSV Filter Rows — filter rows using column values

These tools are useful for:

• developers working with APIs
• data cleaning tasks
• spreadsheet conversions
• automation workflows
• preparing structured data

All tools run locally in the browser, so files are not uploaded to servers.
