Convert TSV to XML Online

Paste a TSV table below, edit it if you need to, and get XML back. The conversion runs in your browser, so nothing is uploaded, there is no size limit and there is no signup.

From a page

The only part of this site that uses a server. The address is sent to it so the page can be fetched, because a browser is not allowed to fetch someone else's page itself. Your own files are never involved.

Nothing here is uploaded. The parsing happens on this page.

Paste or upload something above and it will appear here.

The output will appear here once there is a table to convert.

What TSV is

TSV is CSV with tabs instead of commas. Because tabs almost never appear inside a value, quoting is rarely needed and the files are easier to read by eye.

Bioinformatics, log processing, and anyone who has copied a block of cells out of a spreadsheet: the clipboard format is TSV.

What XML is

XML marks up data with nested named tags and optional attributes. It is verbose, strict about being well-formed, and can carry a schema that says what shape a document must have.

Enterprise integrations, government data feeds, RSS, SOAP services and older document formats.

What changes when you convert TSV to XML

The tab is unambiguous, so there is no delimiter to guess. This is the most reliable of the delimited formats to read.

Each row becomes an element with one child per column. Header names are rewritten where they have to be, because an XML tag cannot start with a digit or contain a space, so a column called 2024 Sales becomes _2024_Sales.

What carries over from TSV to XML

One property of the TSV has no home in XML, and it is worth knowing which before you convert.

XML has no header row. The column names are repeated as keys on every record instead, which is why the result is bigger on disk than the table it came from.

The identifier 007 comes out of the XML as 007. Reading it as a number would have made it 7, and an id that changes value is worse than one that stays text.

The role "Analyst, data" survives with its comma, in one cell rather than split across two. That is the first thing to check in any converted table, and the usual place a XML file goes wrong.

The quotes around Jonah "Jo" Pryce are written as the HTML entity " in the XML.

A worked example

Three rows of staff data, with an identifier that has a leading zero, a value containing a comma, a value containing quotes and one blank cell. Those are the four places formats disagree, so they are the four places to look.

Questions

How do I convert TSV to XML?

Paste your TSV into the box above or drop the file onto it. Check the table in the grid, then copy or download the XML from the output panel. It takes one step and the data never leaves your browser.

Is there a limit on file size?

No. The work happens on your own machine, so the limit is your machine's memory rather than an upload cap. A file with tens of thousands of rows converts in a second or two.

Is my data uploaded anywhere?

No. The parsing and generating are done by JavaScript running on this page. You can watch the network tab while you convert and see that nothing is sent.
