About This Tool
Extract, remove, reorder, and transpose columns across CSV, TSV, and arbitrary delimited datasets directly in your browser without uploading proprietary files to external servers.
Supports matrix transposition (turning rows into columns and columns into rows), arbitrary delimiter swapping (commas, tabs, pipes, semicolons), and quoted cell escaping.
Features an interactive live table preview rendering up to 100 parsed rows with column index badges and real-time dimension counters.
Key Features
- Column Extraction: Select and keep specific columns by 1-based index (e.g. 1, 3, 5) or drop unwanted columns.
- Matrix Transposition: Flip tabular orientation: convert horizontal rows to vertical columns and vice versa.
- Delimiter Conversion: Instantly transform CSV into TSV, semicolon-separated values, or pipe-delimited text.
- Live Table Preview: Inspect formatted tabular data in real time with alternating rows and header styling.
Frequently Asked Questions
How do I extract only specific columns from a CSV file?
Enter the 1-based column numbers into the "Extract Columns" input (for example: "1, 3, 4"). The tool will extract only those columns and rebuild your output.
How does matrix transposition work for uneven rows?
If certain rows have fewer columns than others, the transposer pads shorter cells with empty strings so that all output records maintain symmetrical dimension alignment.
Are my CSV records uploaded to any remote server?
No. All line parsing, regex handling, quoting, and transposition execute 100% locally inside your browser memory.
