Data Tools Online

6 free browser-based tools

Free data tools for CSV, JSON, HTML entities, HTML-to-text conversion, URL parsing and structured cleanup workflows.

Data cleanup tools help turn messy snippets into formats that work in spreadsheets, APIs, documentation, tests, and automation systems. These are the small transformations that often block a larger workflow.

This category focuses on transparent conversion: paste input, see output, copy the result. It is useful for API payloads, CSV exports, HTML snippets, URL parameters, and one-off debugging tasks that do not need a full ETL pipeline.

Use these tools for small and medium data samples where speed, privacy, and clarity matter more than enterprise-scale processing.

Data Tools FAQ

Are these tools for huge production datasets?

They are best for small and medium snippets. Very large datasets should use dedicated data pipelines or local scripts.

Why convert CSV to JSON?

JSON is easier to use in APIs, seed files, scripts, test fixtures, and application imports.

Does HTML escaping sanitize unsafe HTML?

No. Escaping and sanitizing are different. Use a trusted sanitizer when accepting untrusted HTML.
