CSV Viewer

How to use CSV Viewer

1. Choose a CSV file, or paste CSV text into the box below the file picker.
2. Type in the search box to keep only rows containing your text in any column.
3. Click a column heading to sort ascending, again for descending, and a third time to clear sorting.
4. Use Previous and Next to move between pages, and press Download to save the filtered rows as a new CSV.

When a CSV viewer is useful

CSV is the most common way to move tabular data between systems: exports from banks, analytics tools, databases, online stores and government open-data portals are usually CSV. Opening such a file in a text editor shows an unreadable wall of commas, and opening it in a spreadsheet can silently change values, for example by turning long identifiers into scientific notation or stripping leading zeros.

A viewer shows the data exactly as it is stored, in a table, without modifying the file. That makes it useful for a quick look, for finding specific records and for checking an export before importing it somewhere else.

Working with the table

The first row is treated as column headings by default; untick the option if your file has no header row. The status line shows how many rows match your search out of the total and how many columns the file has.

• Search is case-insensitive and matches anywhere inside any cell.
• Sorting applies to the full filtered set, not only the visible page.
• Hover a cell to see its full value if it is truncated.
• Download exports the currently filtered and sorted rows with the header.

Limits and tips

The viewer parses the entire file at once, so very large files may take a few seconds to appear. Only 100 rows are drawn at a time to keep scrolling smooth, but searching and sorting work on all rows. If columns look wrong, the file may use an unusual delimiter or contain inconsistent quoting, so check the raw text.

Character encoding matters: the browser reads files as UTF-8, so a file saved in a legacy encoding may show garbled accents. Re-save it as UTF-8 and open it again. The data stays on your device throughout, which makes this a safe way to look at customer lists, financial exports and other private files.
