About CSV Viewer

Paste CSV data or upload a file to view it as a sortable table. The viewer auto-detects delimiters (comma, tab, semicolon). Click column headers to sort. Use the search box to filter rows. Supports quoted fields and multi-line values.

Frequently Asked Questions

How do I view and sort a CSV file online without Excel?

Upload a .csv, .tsv, or .txt file using the Upload CSV File button, or paste the CSV content directly into the text area. The tool renders the data as a sortable table. Click any column header to sort ascending or descending. Use the search field to filter rows in real time by any value across all columns.

Is my CSV data sent to a server when I upload it?

No. The CSV Viewer reads the uploaded file using the browser’s File API and processes everything in JavaScript locally. Your file content never leaves your device. This makes it safe to view CSV exports containing customer data, financial records, or other sensitive information.

How many rows can the CSV Viewer handle?

The viewer uses pagination (configurable page size) so large files render without displaying all rows at once. However, the entire file is parsed into memory in the browser, so very large files (hundreds of megabytes or millions of rows) may be slow to load or cause the browser tab to run out of memory. For large-scale CSV exploration, use a tool like DuckDB, csvkit, or dedicated BI software.

Does the CSV Viewer support TSV (tab-separated) files?

Yes. The Upload CSV File button accepts .csv, .tsv, and .txt extensions. The parser auto-detects the delimiter by examining the first line of data. If auto-detection fails on an unusual file, you may need to pre-process the delimiter or paste the content with a comma delimiter.

Can I search and filter specific rows in the CSV viewer?

Yes. A search field above the table filters rows in real time across all columns — type any value and matching rows are shown immediately while non-matching rows hide. The filter is case-insensitive. Column-specific filtering is not supported; the search applies globally. For advanced filtering (multiple conditions, column-specific operators), a spreadsheet or query tool offers more control.
