CSV Viewer

Open a CSV or TSV file and read it as a proper table instead of a wall of commas. The viewer detects the delimiter, handles quoted values that contain commas or line breaks, and lets you sort any column, search all rows and page through files with hundreds of thousands of lines without freezing the page.

How to Use the CSV Viewer

  1. Choose a CSV file (or paste CSV text into the box).
  2. Leave the delimiter on Detect automatically or pick comma, semicolon, tab or pipe; untick the header option if the first row is data.
  3. Press View CSV.
  4. Use the column header buttons to sort, the search box to filter rows, and Previous/Next to page through the table.

About This Tool

Analysts checking an export before importing it, developers inspecting a data dump, and anyone who receives a CSV but has no spreadsheet program handy.

Input: CSV / TSV  ·  Output: Table.

Features and Limitations

Features

  • Correct CSV parsing: quoted fields, doubled quotes, line breaks inside cells and CRLF/LF line endings.
  • Click (or press Enter on) a column header to sort ascending or descending; numbers sort numerically.
  • Search filters across all columns as you type.
  • Paging keeps very large files responsive; only one page of rows is drawn at a time.
  • Accessible table markup with column headers and row numbers for screen readers.

Limitations

  • Viewing only: to edit cells, convert to Excel with the CSV to XLSX tool.
  • Up to 100 MB per file; very large files can take a few seconds to parse and use a lot of memory on phones.
  • Values are shown as text exactly as stored (no number or date formatting).
  • Processing happens on your device, so very large files depend on your browser's available memory.

Frequently Asked Questions

My file shows everything in one column. What happened?

The delimiter was probably not detected (for example a file with only one column on the first line). Choose the delimiter manually; European exports often use semicolons.

Can it open files with accented characters?

Yes. UTF-8 files are read directly. Files saved in an older Windows encoding are read as Windows-1252 and the summary tells you so.

Is the data uploaded?

No. Parsing, sorting and searching all happen in your browser.

How do I sort by more than one column?

Sorting is stable: sort by the secondary column first, then by the main column, and rows with equal values keep the earlier order.
