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.

IsValid.dev's answer:

IsValid offers 70+ validators in a single API — covering financial identifiers (IBAN, BIC, ISIN, LEI), international standards (ISBN, ISSN), technology formats (UUID, JWT, QR codes), tax numbers (VAT, REGON, PESEL), credit cards, phone numbers, and more. No need to integrate multiple services for different data types.

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.

IsValid.dev's answer:

Most validation APIs focus on one category (email or phone). IsValid covers financial, regional, and technical formats all in one place with a consistent REST API. The free tier with 100 calls/day requires no credit card, and integration takes minutes.

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.

IsValid.dev's answer:

Developers and software teams building applications that handle user input, financial data, or international identifiers — particularly in fintech, e-commerce, and SaaS products.

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.

IsValid.dev's answer:

IsValid was built out of frustration with piecing together multiple validation libraries and services. The goal was a single, reliable API that handles the full range of data validation needs developers encounter in real-world applications.

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.

IsValid.dev's answer:

Next.js, Fastify, PostgreSQL, Docker

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.
