FAQ Frequently Asked Questions

What file formats does the CSV Column Extractor support?

The tool supports CSV files with various delimiters (comma, semicolon, tab, pipe), TSV files, and text files with structured data. It automatically detects column types (text, number, date) and handles files with or without header rows for maximum flexibility.

How do I reorder and select specific columns from my CSV?

Upload your CSV file, then use the column manager to select/deselect columns with checkboxes. Drag and drop columns in the "Column Order" section to change their sequence. The preview updates in real-time, and you can export only the selected columns in your preferred order.

What export formats are available for the processed data?

Export your customized data as CSV, TSV (tab-separated), JSON, or Excel-compatible formats. Choose whether to include headers, customize the filename, and download the restructured file instantly. All processing happens client-side for data privacy.

Are there any limitations on CSV file size or number of columns?

The tool processes files entirely in your browser, so limitations depend on your device's memory. It handles most standard CSV files efficiently, displaying the first 100 rows in preview for performance while processing all data for export.

Can I preview the changes before exporting the modified CSV?

Absolutely! The tool provides a real-time preview showing your selected columns in the new order. See data statistics, column types, and sample rows before export. The preview updates automatically as you select/deselect columns or change their order.
