Excel Column Operations Are Painful.
We Make Them Instant.
Remove empty columns in one click. Rename 100+ columns with snake_case pattern in 3 seconds. Reorder 60 columns with drag-and-drop. Add conditional if/then columns without formulas. Process 10M+ rows reliably via streaming architecture.
Excel Column Operations: A Special Kind of Hell
Your database exports a CSV with 47 columns. You need 25. The other 22 are empty or irrelevant.
- Click column header A → Scroll right → Is it empty? Check first 20 rows manually
- Right-click → Delete column → Confirm → Wait for Excel to recalculate
- Repeat 22 times (once per empty column)
- Need to reorder? Drag entire column manually — error-prone, no undo
- Need to rename? Click each header, type new name, press Enter. 25 times.
- Need snake_case? Manually type "customer_name", "order_date", "total_amount"... 25 times
- Excel can become unresponsive with many columns on large datasets.
- File has 500K rows. Excel is now unresponsive. Force quit. Lose work.
- Upload CSV (any size, up to 1GB+)
- Click "Remove Empty" button → 22 columns auto-detected, removed in 1 second
- Drag-and-drop remaining 25 columns into correct order (visual grip handles)
- Click "Apply snake_case pattern" → All 25 columns renamed instantly
- Preview shows final layout: first_name, last_name, email, phone, address...
- Click "Download" → Modified CSV ready in 3 seconds
- Process 10M rows reliably (streaming architecture, constant memory)
- Your data never left your browser. Zero uploads. HIPAA compliant.
12 Column Operations Excel Can't Match
Everything you wish Excel could do with columns — in one tool
Select/Extract Columns
Checkbox UI with search. Select 25 out of 100 columns in 10 seconds. Auto-remove empty columns (>90% empty). Preview first 100 rows.
Reorder Columns
Drag-and-drop with visual grip handles. Arrow buttons (↑/↓) for precise control. Reorder 60 columns in 30 seconds.
Bulk Rename (8 Patterns)
Apply snake_case, camelCase, PascalCase, UPPER_CASE, Title Case, slugify, remove special chars, or trim spaces to all columns. Add prefix/suffix.
Add Columns
Static values or conditional if/then rules (11 operators: ==, !=, >, <, >=, <=, contains, starts with, ends with, is empty, is not empty). No formulas.
Delete Columns
Unselect columns (checkbox) or auto-remove empty (one-click). Statistics panel suggests columns >90% empty.
Duplicate Columns
Click copy icon on any column. Creates column_copy with all data. Useful for backup before transformations.
Split Columns
Split by delimiter (comma, space, pipe), regex pattern, or fixed position. Example: "John Doe" → first_name, last_name.
Merge Columns
Combine multiple columns with custom separator. Example: first_name + " " + last_name → full_name.
Column Deduplication
Remove rows with duplicate values in single column. Keep first/last/unique occurrence. Example: Email list cleanup.
Column Statistics
Auto-detect types (number, date, email, url, phone). Show empty %, unique values, min/max/avg/median. Visual progress bars.
Batch Processing
Process up to 20 files (500MB total). Configure operations once, apply to all. Download as ZIP. Retry failed files individually.
Header Sanitization
Auto-remove control characters (tabs, newlines). Deduplicate headers (Email, Email_2, Email_3). Trim whitespace. Validate (max 255 chars).

Is This Tool Right for You?
Perfect For
- Database exports with 30-100+ columns (need to select relevant 10-20)
- API responses needing column standardization (camelCase → snake_case)
- Files too large for Excel (500K+ rows, performance degrades significantly)
- Bulk renaming 50+ columns with patterns
- CRM data migration requiring column reordering
- Email list cleanup via column deduplication
- Conditional column creation without Excel formulas
- Batch processing 12+ files with same operations
- HIPAA/GDPR/SOX compliance (data cannot leave browser)
- Non-technical users who need Python-level power
- Teams without Power Query licenses (Excel 2016+)
- Data analysts spending 2+ hours/week on manual column operations
Not Designed For
- Files with <10 columns (Excel is fine)
- One-off quick column deletion (Excel right-click is faster)
- Complex data transformations requiring custom Python logic
- Database-level column operations (use SQL ALTER TABLE)
- Excel files needing formula preservation (we export CSV)
- Pivot table creation (use our Pivot/Unpivot tool instead)
- Row-level operations (filtering, sorting — use other tools)
- Column math/calculations (use Aggregate/Group tool)
- Data validation or conditional formatting (Excel feature)
- Real-time collaboration (Excel Online/Google Sheets)
- Automated workflows (requires API/scripting)
- Non-CSV formats as input (we accept CSV only)
1M Rows in 30 Seconds
1M rows with 6 simultaneous operations (rename, remove, deduplicate) in 30 seconds. Multi-operation throughput — single-operation speed is significantly higher.
