CSV Viewer

Click the Upload .csv button and choose a file, drag and drop a file anywhere onto the page, or simply paste CSV text directly into the text area. The table renders instantly and everything is parsed locally in your browser.

It follows the standard RFC-style rules: fields wrapped in double quotes may contain commas, quotes (escaped as ""), and even newlines. Only unquoted commas split cells, so data like "Smith, John" stays in one column. This matters for files exported from Excel or Google Sheets.

Yes — click any column header to sort ascending, click again for descending, and a third click clears the sort. Numeric-looking values are compared numerically while text uses locale-aware comparison, so "10" sorts after "9" instead of before it.

When enabled, the first row becomes the column headers and is excluded from the data rows. When disabled, every row is treated as data and columns are labelled Column 1, Column 2, and so on. Header names are trimmed and blank headers are given automatic names.

No. CSV parsing, sorting, and filtering all happen entirely in your browser. The tool works offline, and your data never leaves your device — which makes it safe for confidential spreadsheets.

Use the Copy CSV button to copy the current table (headers plus all parsed rows) to the clipboard, or Download to save it as a .csv file you can open in Excel or any spreadsheet app.
