CSV Viewer — View CSV Online (No Excel)

Why a browser CSV viewer?

Sometimes you just need to peek at a CSV file — a download from an analytics dashboard, a customer export, a survey result — without firing up Excel, waiting for it to load, dealing with column auto-formatting (the famous "01234" → 1234 disaster), or risking the file getting trapped in OneDrive sync. A browser CSV viewer opens the file instantly, shows you what's there, lets you sort and filter, and never touches your data.

Features

• Auto-detects delimiter (comma, semicolon, tab, pipe).
• Sortable columns — click any header.
• Live filter — type in the search box, table filters as you type.
• Big files supported — tested up to ~50k rows.
• No upload, no logging — your CSV never leaves the browser.
• Quoted-field handling — properly parses CSVs with commas/newlines inside quoted cells.

When you'd use this

• Peeking at a customer-export CSV without opening Excel.
• Browsing a sales-data download to check counts and ranges.
• Searching a contact list for one row without loading the whole thing into a spreadsheet.
• Sanity-checking a CSV before importing into another system.
• Reviewing a column's distinct values quickly.
• Sharing a quick CSV view on a meeting screen-share without exposing the source file.

Why not just open it in Excel?

Excel auto-converts cells based on what they look like — turning "01234" into 1234, dates into local format, "5/12" into "May 12 1990", and large numbers into scientific notation. These conversions are silently destructive and can corrupt data you only wanted to view. This viewer treats every cell as text, exactly as it appears in the source file. What you see is what's actually there.
