As answered by people managing Eloquent JavaScript and CSV Cleaner.
CSV Cleaner's answer:
CSV Cleaner focuses on doing one job extremely well: cleaning and deduplicating CSV files fast.
Most alternatives are either:
complex spreadsheet software (Excel/Sheets), or
heavy data tools, or
require scripts or coding.
CSV Cleaner removes all that friction. You just upload → choose options → download.
No formulas, no setup, no accounts required for basic use.
It’s designed to feel like a tiny utility, not a platform.
CSV Cleaner's answer:
Three main reasons:
Speed You can clean a file in seconds without opening Excel or writing pandas scripts.
Simplicity No complicated workflows or dashboards — just the exact tools you need:
remove duplicates
normalize text
clean messy exports
It’s built for people who just want to fix a file quickly and move on with their day.
CSV Cleaner's answer:
CSV Cleaner is mainly for:
freelancers
operations/marketing teams
virtual assistants
founders
analysts
anyone exporting data from tools like Airtable, Stripe, CRMs, or spreadsheets
Basically: people who constantly deal with CSV exports but don’t want to write code.
If you’ve ever thought “why am I doing this in Excel again?” it’s probably for you.
CSV Cleaner's answer:
CSV Cleaner started as a personal frustration project.
I kept getting messy exports from different tools — duplicates, inconsistent formatting, extra whitespace — and I found myself repeatedly opening Excel or writing quick Python scripts just to clean them.
It felt like a problem that should already have a simple solution.
So I built a small web tool to handle the common cases in one click, and kept it intentionally lightweight and boring instead of turning it into a big “data platform.”
The goal was: upload → clean → download → done.
CSV Cleaner's answer:
CSV Cleaner uses a simple, low-ops stack:
Frontend/app built with Lovable
Backend/auth/storage with Supabase
Payments handled by Stripe
Processing happens server-side so files are handled securely and efficiently.
The stack was chosen to ship fast and stay easy to maintain rather than over-engineer.
CSV Cleaner's answer:
CSV Cleaner is still early and primarily used by:
-indie founders
-small teams
-consultants
-ops/marketing folks
-spreadsheet-heavy roles
The tool is intentionally focused on individuals and small teams rather than enterprise customers.
It’s built for everyday workflows, not large corporate pipelines.

Seconded. I won't recommend it and no one I know has recommended it for a decade. It's hard for someone who doesn't know JS to know which parts has changed and is no longer the way to do things. https://github.com/getify/You-Dont-Know-JS... - Source: Hacker News / about 2 years ago
