DBConvert for Excel and MySQL
Remove duplicates, trim whitespace, normalize text โ no Excel required. Get an instant health report, fix duplicates and formatting issues, validate against Stripe, HubSpot, Salesforce, and Shopify, then download a file that's ready to import.
SQLified is a browser-based tool that converts CSV, TSV, and other delimited data files into clean, import-ready SQL โCREATE TABLE plus batched INSERT statements โ for PostgreSQL, MySQL, SQLite, and SQL Server.
Unlike free one-off converters that choke around 100K rows, SQLified is built for production-scale loads: it reliably handles files of 1,000,000+ rows. It does smart type inference (INT/BIGINT, NUMERIC scale, dates, booleans, currency), lets you override any column's type, primary key, and nullability, and emits correctly chunked INSERT batches per dialect (including SQL Server's 1000-row limit and MySQL packet limits) so the output imports cleanly the first time.
Free to use for everyday conversions; Pro unlocks the largest files, batched output tuning, and an ad-free experience. A product of Octet Software.
CSV Cleaner
SQLifiedCSV 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 โ choose options โ download.
No formulas, no setup, no accounts required for basic use.
Itโs designed to feel like a tiny utility, not a platform.
SQLified's answer:
Our ability to infer data types, and produce massive insert statements quickly across multiple dialects.
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 โ just the exact tools you need:
remove duplicates
normalize text
clean messy exports
Itโs built for people who just want to fix a file quickly and move on with their day.
SQLified's answer:
Our tools are simple, effective, and require little processing power. We store no data; all work is "ephemeral" and done on the users machine. We do not track, store, or maintain any datasets whatsoever in regards to whatever is converted on the site. We are also not trying to be something we are not. We do what we do, which is flat file to SQL dialect conversion, and we do it well.
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 donโt want to write code.
If youโve ever thought โwhy am I doing this in Excel again?โ itโs probably for you.
SQLified's answer:
SQLified is designed for the solo developer, or the analytical employee dealing with large data sets, csv, or delimited files every day, and struggling with bulk insert. I want to eliminate that struggle so the real work can be done.
CSV Cleaner's answer
CSV Cleaner started as a personal frustration project.
I kept getting messy exports from different tools โ duplicates, inconsistent formatting, extra whitespace โ 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 โdata platform.โ
The goal was: upload โ clean โ download โ done.
SQLified's answer:
After using many online tools and being disappointed, I realized there was a need for a file that can create clean, type aware sql for bulk inserts. The product saves me tons of time every month dealing with large data sets in the payment industry and has reduced frustrations in dealing with them.
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.
Itโs built for everyday workflows, not large corporate pipelines.
SQLified's answer:
There are numerous competitors, but none that do what SQLified does well: this is type inference, and creating runnable SQL script for extremely large inserts in multiple dialects.
