Clean Your Data, Not Your Calendar
CSV Studio is a visual, deterministic data cleaning tool that lets you build reusable transformation pipelines without writing code.
Transform messy data into clean data in minutes — privacy-first, browser-based, deterministic.
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 pipelines 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 CSV Studio Solution
- ✓Visual pipeline builder - see your entire workflow at a glance
- ✓Reusable profiles - 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
Upload Your File
Drag and drop your CSV, Excel, or XML file. Your data stays in your browser.
Build Your Pipeline
Add transformation nodes like trim, filter, dedupe, and validate. Connect them visually.
Export Clean Data
Preview results in real-time, then export to CSV, JSON, Excel, or XML.
Powerful Transformations
Basic Transformations
Select Columns
Choose which columns to keep, drop, or rename. Reorder columns as needed.
Trim & Clean
Remove leading/trailing whitespace and collapse multiple spaces.
Case Transform
Convert text to lowercase, UPPERCASE, or Title Case.
Date Convert
Parse dates and convert between formats (e.g. MM/DD/YYYY to YYYY-MM-DD).
Data Quality
Dedupe
Remove duplicate rows based on key columns.
Filter Rows
Keep or remove rows based on conditions (equals, contains, greater than).
Validate
Apply validation rules and optionally reject invalid rows.
Fill Empty
Replace empty values with constants, previous values, or calculated values.
Advanced Transformations
Find & Replace
Search with regex patterns and replace text across columns.
Computed Columns
Create new columns using formulas (concat, math, conditionals).
Split Column
Split one column into multiple based on a delimiter.
Merge Columns
Combine multiple columns into one with custom separator.
