CSV Preview & Quick Edit

Clean messy CSVs in Chrome: find/replace, dedupe, fix emails, edit cells, export to CSV, TSV, JSON, XLSX, Markdown. Local.

🎯 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. 👥 PERFECT FOR 📊 Data analysts doing quick sanity checks on datasets before importing them into larger tools 💻 Developers inspecting API response dumps, database exports, or log files in CSV format 📈 Marketers reviewing audience exports from ad platforms, email tools, or analytics dashboards 💰 Accountants and finance teams checking transaction exports before running imports 📦 Operations teams editing supplier lists, inventory files, or shipping manifests 🎓 Students and researchers working with research data, survey results, or class grade exports ✨ KEY FEATURES ✅ Instant CSV rendering — opens CSV files as a formatted, readable table directly in your browser ✅ Auto-detect delimiters — commas, semicolons, tabs, and pipes recognized automatically ✅ Sortable columns — click any column header to sort the entire table ascending or descending ✅ Inline cell editing — double-click any cell to edit its value without leaving the browser ✅ Filter and search — type to filter rows dynamically and find specific records instantly ✅ Row selection — select individual rows or bulk-select for copy or delete operations ✅ CSV export — download the current table as a clean CSV file after edits ✅ Clipboard copy — copy selected rows or the entire table to clipboard as CSV ✅ Column resize — drag column borders to adjust widths for comfortable viewing ✅ Pagination — smooth page-by-page navigation for large files ✅ 100% local processing — your data never leaves your browser, guaranteed 📖 HOW TO USE → Click the CSV Preview & Quick Edit icon in your toolbar → Click "Open CSV File" and select any .csv, .tsv, or .txt file from your computer → Your file opens as an interactive table in a new tab → Sort, filter, edit, and export as needed → Navigate to any CSV URL and the extension auto-detects it 💡 PRO TIPS 💡 Use Tab while editing a cell to quickly move to the next column 💡 Click the column header twice to reverse the sort direction 💡 Use the search bar for instant full-text filtering across thousands of rows 💡 Select multiple rows with checkboxes, then copy or delete in bulk 💡 The extension remembers your last 20 opened files for quick re-access ❓ FREQUENTLY ASKED QUESTIONS Q: Does it work with large CSV files?
