About RowLab
Transform messy data into clean data in minutes
Clean Your Data, Not Your Calendar
RowLab is a visual, deterministic data cleaning tool that lets you build reusable transformation workflows without writing code.
100% Deterministic
No AI guesswork. Same input, same output, every time. Your data transformations are predictable and reproducible.
Privacy-First
Your data stays local. Files are processed entirely in your browser - nothing is uploaded to any server.
Save Hours
Build reusable workflows once, run them on any file with the same structure. No more repetitive manual cleaning.
Handle Any Format
Import CSV, Excel, TSV, XML. Export to multiple formats. Work with the tools you already use.
Why Not Just Use Spreadsheets?
The Spreadsheet Problem
- ×Spreadsheets mix data with logic - impossible to reuse on new files
- ×Manual point-and-click is error-prone and tedious
- ×No audit trail of what changed
- ×Formulas break when data structure changes
- ×Hard to maintain consistency across team members
The RowLab Solution
- Visual workflow builder - see your entire cleanup at a glance
- Reusable workflows - apply the same cleaning steps to any file
- Execution receipts - know exactly what changed
- Non-destructive - original data is never modified
- Export clean data in any format you need
How It Works

Drag and drop your CSV, Excel, or XML file. Your data stays in your browser.
Build Your Workflow
Add transformation steps like trim, filter, dedupe, and validate. Connect them visually.
Export Clean Data
