Questions & Answers

As answered by people managing HowToCSV and Diffee.

Which are the primary technologies used for building your product?

HowToCSV's answer

To ensure privacy and security, all computation occurs client-side, directly on the user's local machine. To achieve this, the entire system uses only client-side technologies, starting with NextJS and extending to WASM modules with in-memory analytics DBs for complex transformations and manipulations: no data ever leaves the user's computer.

What makes your product unique?

HowToCSV's answer

"iLovePDF for CSV files": a single place with lots of tiny browser-based utilities for anything you might need to do with tabular CSV data without installing heavy software or writing code. It’s focused on real quick hacks: merge, unpivot, clean, convert, forecast, generate synthetic scenarios, etc. and all in the browser.

Why should a person choose your product over its competitors?

HowToCSV's answer

Even if you hate CSVs, you'll love what we can do with them!

Zero installs — tools run directly in your browser.

Lots of small focused utilities in one place instead of searching for separate converters or editors.

Free access to basic CSV processing tasks up to a modest file size.

Quick one-off fixes (dedupe, pivot, unpivot, simple transforms) without scripting or spreadsheets.

How would you describe the primary audience of your product?

HowToCSV's answer

Folks who work with tabular text data but don’t want to fire up Excel or write scripts. Data analysts, product people, devs doing quick transformations. Students, hobbyists, or anyone needing simple CSV work without local tooling.

What's the story behind your product?

HowToCSV's answer

It started as a side project by a builder tired of fighting with Excel and separate utilities for simple CSV tasks. Put together ~30 tools from other projects he’d built, wrapped them into one free toolkit, and launched it as ilovecsv.net end of 2025. It gained organic search traction quickly.
