CSV Viewer Pro

Upload, inspect, edit, and export CSV data directly in your browser. Perfect for data analysts, engineering, and research teams alike.

Import options

Switch between manual uploads, fetch CSVs from a secure URL, or use sample data.

Choose CSV or drag & drop .csv files up to~5MB

We don't store your file. Fetch happens client-side, subject to source CORS rules.

Flexible ingest

Drag, drop, or fetch

Upload locally or paste a URL. Client-side parsing keeps sensitive data off servers.

Spreadsheet UX

Inline editing

Sort columns, edit cells, and lock in clean data before exporting anywhere else.

Exports

CSV + Excel-ready

Download the entire dataset, Excel-compatible BOM files, or just the rows you filtered.

Quick checklist

  1. 1. Import: upload or fetch your CSV, no account needed.
  2. 2. Review: scan the table, sort columns, update rows inline.
  3. 3. Filter: search, trim ranges, or add new entries in context.
  4. 4. Export: grab the clean CSV/Excel file or share a specific slice.
