Preview and explore CSV files as a formatted table — free, instant, no signup required
or click to browse — max 20MB
A CSV Viewer is an online tool that opens and displays CSV files as clean, formatted tables directly in your browser — no Excel, Google Sheets, or other software required. The FileTools CSV Viewer parses your file entirely client-side using JavaScript, which means your data never leaves your device. This makes it the safest option for previewing sensitive spreadsheet data like customer lists, financial records, or confidential exports. The viewer auto-detects common delimiters (comma, semicolon, tab, pipe), highlights search matches, paginates large files, and shows statistics like row count, column count, and file size — all without any installation or signup.
Common use cases: quickly previewing CSV exports without opening Excel; checking the structure of unfamiliar CSV files before importing them into databases; viewing CSV files on machines without spreadsheet software (kiosks, lightweight laptops, locked-down work computers); searching through large CSV exports for specific values; reviewing data before processing in scripts or pipelines; sharing CSV previews securely on devices where you don't want to install software; and inspecting CSV files received from clients, vendors, or downloads when you're not sure if they're safe to open.

No. The CSV Viewer parses your file entirely in your browser using JavaScript. Your data never leaves your device — nothing is uploaded, stored, or transmitted. This makes it the safest option for previewing sensitive spreadsheet data.
Yes. Type any keyword in the search box above the table to instantly filter rows that match. Matching text is highlighted in blue. The pagination updates automatically to reflect filtered results.
The viewer auto-detects the most common delimiters — comma, semicolon, tab, and pipe. You can use it to view standard CSV files, European-style CSV (semicolon), TSV (tab-separated), and pipe-delimited files without manual configuration.
The CSV Viewer handles files up to 20MB. Larger CSVs may slow down browser performance since the entire file is loaded into memory. For files beyond 20MB, consider splitting them first using our CSV Splitter tool.
