CSV Viewer
Open a CSV or TSV file as a sortable, searchable table right in your browser — no spreadsheet needed.
Drop a CSV or TSV file — or click to browse
Paste CSV above or drop a file to see it as a table.
How it works
Drop a .csv or .tsv file — or paste the raw text — and it is rendered
as a real table straight away, no spreadsheet program required. The parser follows RFC 4180, so
quoted fields containing commas, line breaks and doubled "" quotes stay in one
cell, and the delimiter (comma, semicolon, tab or pipe) is detected automatically. Click any
column heading to sort it — columns whose values are all numeric sort numerically instead of
alphabetically — and use the search box to filter across every column at once. Large files are
paged so the browser stays responsive.
Copy or download whatever you are currently looking at: the export follows your search filter and sort order, so you can pull a slice of a big export without touching Excel. Everything runs locally in your browser with JavaScript — the file is never uploaded, stored or logged, which makes it safe for exports containing customer or financial data.
Frequently asked questions
How do I open a CSV file without Excel?
Drop the .csv or .tsv file onto this page — or paste the raw text — and it is rendered as a table immediately. Nothing is installed and nothing is uploaded: the file is parsed by JavaScript inside your own browser tab, so it works on a locked-down work laptop or a phone where no spreadsheet program is available.
Is it safe to open a CSV file in an online viewer?
With this one, yes. Parsing, sorting and searching all happen locally in your browser, so the file never leaves your device and is never stored or logged. That matters for CSV exports, which usually contain customer records, orders or payroll data — many other online CSV viewers upload the file to their server first.
Why are my columns all squashed into one, and can I sort them?
That happens when the file uses semicolons, tabs or pipes instead of commas — common in European Excel exports. The delimiter is auto-detected, and you can override it from the Delimiter menu if the guess is wrong. Click any column heading to sort; columns whose values are all numeric sort numerically rather than alphabetically, and Copy or Download exports exactly the filtered and sorted rows you are viewing.
