CSV Viewer
Open any CSV file in your browser: paste the text or upload the file, and this CSV viewer shows it as a clean table you can search and sort. It detects commas, semicolons and tabs, handles quoted fields, and nothing leaves your computer.
What Is a CSV Viewer?
A CSV Viewer for Plain-Text Tables
A CSV viewer turns comma-separated text into rows and columns, so you can read the data without opening a spreadsheet program or squinting at commas. Long cells are trimmed in the table; hover over one to read it in full.
Delimiters and Quoted Fields
Commas, semicolons, tabs and pipes all work, and fields wrapped in double quotes, including ones that contain line breaks, are kept together.
Search, Sort and Count
Filter rows by any text, sort by clicking a column title, and see the number of rows and columns at a glance. Numbers sort by value rather than as text, so 10 comes after 9.
Why Use Our CSV Viewer?
An Online CSV Viewer, Nothing to Install
The CSV viewer opens in any browser on a laptop or a phone, so a file from a colleague is readable in seconds. Exports from survey tools, lab instruments and databases all open the same way.
Private by Design
Files are parsed on your device and never uploaded, which matters for survey responses, grades or customer data.

Step 1: Paste or Upload
Paste the text into the box, or upload a .csv, .tsv or .txt file of up to 20 MB.
Step 2: Check the Settings
The CSV viewer guesses the delimiter and the header row; change either one if the table looks wrong. The counts above the table confirm that every row was read.
Step 3: Search and Sort
Type in the search box or click a column title to sort, then scroll through the result.

CSV Viewer FAQ
- What is a CSV file?
- A plain-text file of comma-separated values: each line is a row and commas split it into columns, usually with column names on the first line. Almost every spreadsheet, database and statistics program reads and writes it. The name comes from the comma, though semicolons and tabs are common too.
- How to create a CSV file?
- Save a spreadsheet with File, Save As and the CSV format, or type values separated by commas into any text editor and save it with a .csv extension. Paste the result into the CSV viewer to check it. Choose UTF-8 when the program asks, so accented names survive.
- How to open CSV file?
- Spreadsheet programs open CSV files directly, and any text editor shows the raw text. For a quick look without installing anything, upload or paste it into this CSV viewer. Opening a file in the CSV viewer never changes it.
- How to convert CSV file to XLSX?
- Open the CSV in a spreadsheet program and save it as a workbook. To turn it into a table for a paper instead, the Excel to LaTeX tool converts CSV straight to LaTeX. Check dates and long numbers after converting, since spreadsheets sometimes reformat them.
- How do CSV files work?
- There is no hidden structure: a CSV file is text, one record per line, fields separated by a delimiter, and fields that contain the delimiter or a line break wrapped in double quotes. That simplicity is why the format has lasted for decades.
- How to combine multiple CSV files into one?
- If the files share the same columns, keep the header from the first and append the data rows of the others. A spreadsheet, a text editor or a short script can do it; check the result here in the CSV viewer. Watch for a second header line left in the middle of the data.
- How to download CSV file?
- Websites and apps usually offer it under Export or Download, with CSV as one of the formats. Once it is saved, drop the file into the CSV viewer to look inside. Some exports use semicolons, which the viewer detects for you.
- What does a CSV file look like?
- Like plain text with commas: a header line such as name,score,city followed by one line per record. This CSV viewer shows the same data as a table with numbered rows.
- How to format a CSV file?
- Use one header row, the same number of fields on every line, double quotes around fields with commas or line breaks, and UTF-8 encoding. Rows with missing fields show up here as blank cells. Avoid merged headers and notes above the table, which most programs read as data.
- How to add password to CSV file?
- CSV is plain text and has no password feature. Put the file in an encrypted ZIP archive, or keep it in a protected folder, if it holds sensitive data.
- Do CSV files have headers?
- They often do, but it is not required. Untick First row is a header if your file starts straight with data, and the columns are numbered instead.
- Can I view a large CSV file online?
- Yes, files of up to 20 MB open in the browser. The CSV viewer shows the first 1,000 matching rows at a time; use the search box to reach specific records in the rest. Sorting and searching stay quick even with tens of thousands of rows.
- Do I need to install a CSV viewer?
- No. This CSV viewer runs in any modern browser on Windows, Mac, Linux or a phone, with nothing to download and no account.
- Can I edit the CSV in this viewer?
- The table is for reading, searching and sorting. Edit the text in the box above, or change the file in a spreadsheet, and the table updates straight away. Copy the corrected text back into your file when you are done.
- Does it read semicolon and tab separated files?
- Yes. It detects commas, semicolons and tabs from the first line, and you can choose any of them, or a pipe, by hand if the guess is wrong. The CSV viewer re-reads the data whenever you change the setting.
- How does the viewer handle the header row?
- By default the first row becomes the column titles, which you can click to sort. Untick the option to treat that row as ordinary data. Headers that repeat or are blank are shown as they are, so problems are easy to spot.
- Can I turn a CSV file into a LaTeX table?
- Yes. The Excel to LaTeX tool takes CSV or TSV and returns a booktabs table ready for your paper.
- Is my CSV file uploaded anywhere?
- No. Your browser reads and displays the file, and none of its contents are sent to a server.
