Questions & Answers

As answered by people managing CSV Cleaner and Rectangle.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

CSV Cleaner's answer

Three main reasons:

  1. Speed You can clean a file in seconds without opening Excel or writing pandas scripts.

  2. Simplicity No complicated workflows or dashboards — just the exact tools you need:

remove duplicates

normalize text

clean messy exports

  1. Low friction Free tier, no signup required to try it, and simple pricing (not credit-based or usage tricks).

It’s built for people who just want to fix a file quickly and move on with their day.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?

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.
