CSV Viewer — Open It as a Table, Read It Properly

A CSV file is a spreadsheet saved as plain text, and opening one should be trivial — until the names come out as “ÇѱÛ” or “é”, the columns shift halfway down, or the file is too big for Excel to be pleasant. This viewer opens CSV and TSV files as a real table you can sort and filter, tells you in plain English what the table holds, and reads the file in the encoding it was actually saved in. That last part is the one most viewers skip: Excel on Windows has long saved CSV in the computer’s older regional format rather than UTF-8, which is why a Korean, Japanese or accented export turns to garbage elsewhere. It is detected and read correctly here, and one click saves a copy that opens properly in Excel anywhere. The file is processed entirely in your browser — customer lists and exports never leave your device.

Garbled Text Fixed

Excel exports saved in Korean, Japanese, Chinese or Western legacy encodings are detected and read correctly, then saved back as UTF-8 Excel opens anywhere.

Explained in Plain English

A summary says how many rows and columns there are, which columns hold numbers or dates, where the blanks are, and which column is probably an ID.

A Real Table

Sort any column — numbers sort as numbers — filter every row by a word, and page through files far larger than you would want to scroll.

Never Uploaded

Customer lists, sales exports and survey results are read in your browser. Nothing is sent to a server, and you can check.

!How It Works, Step by Step

1

Drop a .csv or .tsv file, or paste CSV text. It is read in your browser — nothing is uploaded.

2

Read the summary: rows, columns, what each column holds, and any rows that do not line up.

3

Sort by clicking a column heading, or type in the filter box to find rows containing a word.

4

If the text was garbled, it is already fixed — click Download for Excel (UTF-8) to keep a copy that opens correctly.

Technical FAQ

How do I open a CSV file without Excel?
Drop it onto this page. It opens as a table you can sort and filter, with a plain-English summary of what it holds, and it works the same on Windows, Mac, Linux or a Chromebook. Nothing is installed and nothing is uploaded: the file is read and processed entirely in your browser.
Why does my CSV show strange characters like “é” or “ÇѱÛ”?
Because the file was saved in one encoding and opened in another. Excel on Windows has long saved CSV in the computer’s older regional format — EUC-KR on a Korean system, Shift_JIS on a Japanese one, Windows-1252 on a Western one — while most other software assumes UTF-8. This viewer detects when a file is not UTF-8 and reads it in the format it was really saved in; if the guess is wrong, you can pick the encoding yourself. Download for Excel then saves a UTF-8 copy with the marker Excel needs to read it correctly.
How do I fix a CSV that shows garbled text in Excel?
Open it here first. Once the text reads correctly on this page, click Download for Excel (UTF-8). That file carries a byte-order mark — a short invisible marker at the start — which tells Excel the file is UTF-8, so Korean, Japanese, Chinese and accented characters display properly when you double-click it.
Is it safe to open a CSV with customer data here?
Yes. The file is processed entirely in your browser: it is read from your disk into the tab and never sent to a server. You can verify it — open your browser’s developer tools, watch the Network tab while you load the file, and no request carries it. That is the point of doing this locally for customer lists, payroll exports and survey results.
Why are some of my columns shifted to the right?
Usually a value contained the separator — a comma inside an address or a name like “Kim, Min-jun” — and was not wrapped in double quotes, so it split into two cells. The viewer names the rows whose cell count differs from the header row, so you can find them. Correctly quoted values, including ones containing commas or line breaks, are read as single cells.
Can it open TSV and semicolon-separated files?
Yes. The separator is detected automatically — comma, semicolon, tab or pipe — by checking which one gives every row the same number of cells. European Excel versions often use semicolons because the comma is their decimal mark. You can also set the separator yourself if a file is ambiguous.
How large a CSV file can it open?
Files with hundreds of thousands of rows open, because the table shows a hundred rows at a time instead of drawing them all. Sorting and filtering work across the whole file. The limit is your own device’s memory, since the file never goes to a server that could do the work instead.
Can I convert a CSV to JSON?
Yes. Download as JSON saves the table as a list of records, each keyed by the column headings — the shape most programs and APIs expect. Open the result in the JSON viewer if you want to check it.
