About This Tool
When working with database dumps, server access logs, or spreadsheet exports, data files frequently contain extraneous fields, mismatched delimiters, or inconvenient column orderings. Rather than opening heavy desktop spreadsheet software or writing throwaway command-line scripts, this browser utility extracts specific column subsets, swaps column positions, transposes rows and columns, and converts between delimiter standards directly in memory.
### Data Manipulation Operations - Delimiter Conversion: Convert between Comma (CSV), Tab (TSV), Semicolon (;), Pipe (|), or custom character delimiters. - Column Extraction: Extract specific column indices using comma-separated numbers (such as 1, 3, 4 to keep only the first, third, and fourth columns). - Column Swapping: Exchange the positions of any two columns (for example, swapping column 1 and column 2 to place identifiers before names). - Matrix Transposition: Rotate tables 90 degrees so that horizontal rows become vertical columns and vertical columns become horizontal rows. - Line Hygiene: Automatically trim leading and trailing cell whitespace and drop empty blank lines.
### Worked Transformation Example Suppose you receive an e-commerce order export with five columns:
Raw Input Data (CSV): order_id,customer_name,item,amount,status 1001,John Doe,Laptop Stand,49.99,Completed 1002,Jane Smith,Mechanical Keyboard,129.50,Completed 1003,Bob Johnson,USB-C Hub,34.00,Shipped
Operation: Extract columns 1, 2, 4 with a Tab (TSV) output delimiter:
Transformed Output: order_id customer_name amount 1001 John Doe 49.99 1002 Jane Smith 129.50 1003 Bob Johnson 34.00
Unnecessary item descriptions and order status flags are stripped, producing a clean three-column tab-delimited file ready for accounting import.
### Client-Side Processing Guarantee All string splitting, column extraction, delimiter replacement, and matrix transformations execute locally in your web browser memory. No sensitive customer records, employee logs, or financial data are uploaded to external cloud servers.
How to Use
- 1
Paste your delimited text (CSV, TSV, Pipe, or custom) into the input editor.
- 2
Confirm your input delimiter (comma, tab, pipe, semicolon, or custom).
- 3
Choose your output delimiter and specify columns to extract (e.g. 1, 2, 4).
- 4
Copy the transformed output or download it directly as a text file.
Frequently Asked Questions
How do I extract non-consecutive columns?
Enter comma-separated 1-based column indices into the column selection box (for example: 1, 3, 5). The tool outputs only those columns in the specified order.
Can I convert a CSV file to a pipe-delimited format?
Yes. Select Comma as the input delimiter and Pipe (|) as the output delimiter to automatically replace delimiters across every line.
Is my confidential spreadsheet data uploaded to a server?
No. All text parsing and delimiter transformation execute 100% in your local browser sandbox.
