Frequently Asked Questions
How does the CSV viewer work?
Paste your CSV data into the text area or upload a .csv file. The tool parses the data, detects the delimiter automatically (or use the dropdown to specify), and renders it as an interactive HTML table. You can click column headers to sort, use the search box to filter rows, and scroll through large datasets.
How do I sort columns?
Click any column header to sort by that column. Click once for ascending order (AโZ, 0โ), click again for descending order. A small arrow indicator shows the current sort direction. The tool intelligently detects whether a column contains numbers or text and sorts accordingly โฆnumbers sort numerically, text sorts alphabetically.
How does the search filter work?
Type any text into the search box and the table instantly filters to show only rows containing that text in any column. The search is case-insensitive and matches partial text. For example, searching "john" will match "John Smith" and "Elton John". The filtered row count is displayed next to the total.
What delimiters are supported?
Comma (default), semicolon, tab, and pipe. Auto-detect analyzes the first few lines and picks the delimiter that produces the most consistent column count. Semicolon is common in European locales where the comma is the decimal separator. Tab-delimited files (TSV) are also fully supported.
How are quoted values handled?
The parser follows RFC 4180 standards. Values wrapped in double quotes are treated as single fields, even if they contain the delimiter character or newlines. Embedded double quotes are unescaped (doubled quotes "" become single "). This ensures proper handling of complex CSV data with commas or line breaks inside fields.
Is this tool free?
Yes, completely free with no sign-up required. All processing happens in your browser โฆyour data is never uploaded to any server.
