Common use cases
Read raw CSV cleanly
Open a comma-separated file as a proper table instead of a wall of commas in a text editor. Column alignment and headers make even a messy export instantly readable.
Check delimiters & encoding
Unsure if a file is comma, semicolon, or tab separated? The viewer parses it and shows the result, so encoding or delimiter problems are visible before they break an import.
Inspect large exports
Preview a big CSV dump — orders, logs, contacts — to confirm the columns and row count are what you expect before feeding it into a database or analytics tool.
Open a CSV without a spreadsheet
A CSV is plain text, which makes it easy for machines and awkward for people. A text editor shows commas instead of columns; a spreadsheet shows columns but often mangles them on the way in, turning product codes into dates and stripping the leading zeros off identifiers.
This viewer reads the file and lays it out as a table: one row per record, one column per field, values exactly as they were written. Nothing is installed and no account is created, and the page behaves the same on a phone, a Chromebook or a locked-down work laptop.
Delimiter and encoding problems, solved on open
Two things break more CSV files than anything else, and both are handled before you see the table.
The delimiter is the first. A file that opens as a single wide column has one your tool did not expect — usually a semicolon, standard across much of Europe, or a tab from a database export. Comma, semicolon and tab are all detected here.
The encoding is the second. Older exports store text in a regional code page rather than UTF-8, which is why names come back full of question marks or boxes. Several encodings are tried in order, so text usually renders correctly on the first attempt.
A title line above the header is skipped too, so an export that begins with a report name opens as a table rather than one column of run-together text.
Reading a large export without loading it
The table shows a type label on every column header — number, date or text. This is the fastest way to catch the mismatch that breaks a later import: a column that looks numeric but is stored as text, or a date that did not parse because it uses a local format rather than ISO.
Rows are paginated so a file with tens of thousands of records stays responsive, and a search box filters across every column at once — the quickest way to answer "is this order id in the export?" without scrolling.
Values are shown as written. Long identifiers keep their leading zeros and product codes stay codes, rather than being reformatted the way a spreadsheet import often does.
When you want more than a look
A charts tab sits beside the table, so the same file can be inspected and then visualised without a second upload. Exports to CSV and JSON are above the grid if you need the parsed data elsewhere — converting an awkward semicolon-delimited, legacy-encoded export into clean UTF-8 CSV or JSON is often reason enough to open it here.
Your file is parsed and returned as data rather than kept in permanent storage, and your file history stays in your own browser. For files under a strict confidentiality obligation, use the software your organisation has approved.
Tips & best practices
A CSV displays as a clean table when its first row holds column names and each row has a consistent field count. The viewer auto-detects common delimiters (comma, semicolon, tab); if columns run together, the file likely uses an unusual separator or has unquoted commas inside fields. Choose UTF-8 encoding to render accents, emoji, and non-Latin scripts correctly — a file saved in a legacy code page may show garbled characters. Fields containing commas or line breaks should be wrapped in double quotes so they stay in one cell. A title line above the header is skipped automatically, so a report export opens as a proper table without editing. Your file is parsed and returned as data rather than kept in permanent storage, and your file history stays in your own browser.

Q.What does this site do & how can I convert my CSV files to graphs?
This site is a free, instant online tool to view, read, and convert CSV (.csv) files into interactive charts. Simply upload your file in the box above, and our system will automatically analyze your data structure, detect column types, and generate chart recommendations which you can customize and export.
Q.What file types are supported?
.csv files are supported.
Q.What chart types can it generate?
Bar, line, area, pie, scatter, and trend charts — chosen automatically based on your data.
Q.Is it free?
100% free. No signup, no credit card, no limits.
Q.Why does my CSV open as a single column?
The file uses a delimiter your previous tool did not expect, usually a semicolon or a tab. All three common delimiters are detected here, so it opens as a proper table.
Q.Can it open a file with a title row above the header?
Yes. Title rows and blank lines above the real header are skipped automatically, which is the usual shape of report exports.
Q.Will it mangle my product codes or leading zeros?
No. Values are displayed as written, so identifiers keep their leading zeros instead of being reformatted the way a spreadsheet import often does.
Q.My accented characters look wrong. Can that be fixed?
Several encodings are tried automatically, so most legacy files render correctly. If they still do not, re-saving the source as UTF-8 resolves it permanently.
Q.How large a file can it open?
Large exports open in full. Rows are paginated so the page stays responsive rather than trying to draw everything at once.
Have a different file type?
Each format has its own dedicated tool built for it.
