I Built 30 Browser-Based CSV Tools for Developers

CSV is one of those formats that developers work with constantly.

Importing data, cleaning exports, converting formats, checking rows, extracting columns, comparing files — most of these tasks are simple, but I often found myself searching for a different online tool for each one.

So I decided to build my own collection.

MegaSimplify now has 30 CSV tools, including:

CSV Viewer & Analyzer
CSV Editor & Cleaner
CSV Validator
CSV Sorter, Filter & Search
CSV Find & Replace
CSV Splitter & Merger
CSV Compare
CSV Remove Duplicates
CSV Column Extractor & Reorder
CSV Header Editor
CSV Transpose
CSV Delimiter Converter
CSV → JSON / XML / SQL / HTML
CSV ↔ Base64
Random CSV Generator

The goal is to keep these tools fast, simple, and accessible directly from the browser.

No account required. No installation. Just open the tool and work with your data.

I'm continuing to build and improve the collection, and I'm particularly interested in feedback from developers who regularly work with CSV data.

What CSV operation do you find yourself doing repeatedly?

And is there a CSV tool you'd like to see added?

I Built MegaSimplify: 200+ Free Browser-Based Tools in One Place

I recently launched MegaSimplify, a free collection of online tools designed to make everyday digital tasks faster and easier.

The project includes tools for developers, creators, students, and general users — including JSON formatting, CSV conversion, image tools, PDF tools, calculators, text utilities, SEO tools, and more.

One of my main goals is to keep as many tools as possible 100% client-side, so users can process their data directly in the browser without unnecessarily uploading files to a server.

I'm still actively building and improving the platform.

I'd love feedback from the DEV community:

Which tools would you find useful?
What features should I add?
Is there anything about the UI/UX you'd change?
Are there developer tools you'd like to see?
I'm sharing the project because I'd like to learn from other developers who have built and launched their own web projects.
