Csv Preview Quick Edit

🎯 WHY CSV PREVIEW & QUICK EDIT

Every day, millions of CSV files get downloaded from analytics dashboards, CRMs, bank portals, and data exports. Your browser shows them as a wall of raw comma-separated text that is impossible to read. Opening them properly means launching Excel, importing into Google Sheets, or waiting for a heavyweight application to start.

CSV Preview & Quick Edit changes this entirely. It turns your browser into a lightweight, instant CSV viewer and editor. No uploads, no sign-ins, no waiting. Open the extension, pick your file, and your data appears as a clean, sortable, editable table in under a second.

🚀 HOW IT WORKS

▸ Open any CSV file through the extension popup or navigate to a CSV URL — the extension automatically detects it and offers to render it as an interactive table.

▸ Columns are identified, headers are extracted, and delimiters are auto-detected. Commas, semicolons, tabs, and pipes all work out of the box.

▸ Click any column header to sort ascending or descending. Use the search bar to filter across all rows instantly.

▸ Double-click any cell to edit its value inline. Tab to the next cell, Enter to confirm, Escape to cancel. Modified cells are tracked so you know exactly what changed.

▸ When you are done, export the result as a clean CSV file ready for upload or further processing.
