Our Mission
Data quality shouldn't be an afterthought. We believe every organization deserves reliable, validated data that powers confident decision-making—without compromising privacy.
Privacy First
Your data never leaves your computer. Complete privacy and control with enterprise-grade validation running entirely in your browser using File System Access API.
Performance Focused
WebAssembly validation engines provide high-performance validation. Offline-capable PWA with Service Workers.
Developer Experience
Intelligent schema generation with 6 data types, RFC 4180 strict compliance, and detailed error reporting with row/column locations.
Our Story
The Problem: Real Teams, Real Pain
"We receive CSV files via email from partners. They often have encoding issues or data corruption from Excel."
"Our ETL jobs fail regularly because incoming CSV files have structural issues. We spend hours debugging."
"We're setting up a new data transfer process but can't clearly define what a valid CSV file looks like."
Every data team faces these challenges. CSV files arrive with quality issues that break systems, corrupt databases, and waste engineering time. Traditional tools either lack enterprise-grade validation or require uploading sensitive data to cloud services—compromising privacy.
Our Solution: Privacy-First Validation
CSV Workbench was built to solve these real problems without compromising privacy. Your data never leaves your computer. We built intelligent schema generation, WebAssembly validation engines, and RFC 4180 strict compliance into an offline-capable Progressive Web App.
For manual file review, validate instantly in your browser (Chrome 86+ or Edge 86+ on laptop/desktop). Edit files directly without spreadsheet corruption. Generate schemas to validate future files.
For automated workflows, create data contracts using CSV Schema. Share schemas with data providers. Integrate server-side validation engines (AWS or Azure) into your ETL pipeline to reject bad files before they reach your systems.
Looking Forward: Enterprise Integration
The free web application solves most CSV validation needs—completely local, no sign-up required. For enterprise teams needing automated validation in their infrastructure, we're expanding with server-side validation engines via AWS and Azure marketplaces.
Our commitment remains unchanged: your data stays where it belongs—on your computer for the web app, in your cloud infrastructure for server-side engines. Privacy and data control are non-negotiable.
