CSV to XML Converter
This CSV to XML converter turns every row into one element inside a single wrapper element, because XML documents need exactly one root, and turns every column into a child element named after its header. Spreadsheet headers routinely look like First Name, 2026 Total or Price (USD), none of which are legal XML element names — those characters are replaced with underscores and a leading digit gets an underscore prefix, so the output always parses rather than failing when the receiving system reads it. Both element names are configurable, the delimiter can be comma, semicolon, tab or pipe, and numeric and boolean cells are converted to real values. Everything runs in your browser.
How it works
Each row becomes one element, and each column becomes a child element named after its header. Column names that are not valid XML names — ones with spaces or a leading digit — are rewritten with underscores.
Rename the wrapper and row elements below to match whatever schema you are feeding.
The conversion runs entirely in your browser — nothing you paste or upload is sent to a server.
How to convert CSV to XML
- Paste your CSV, or upload a
.csv/.tsvfile. - Set the delimiter if the file does not use commas, and say whether the first row holds column names.
- Name the wrapper and row elements to match the schema you are targeting.
- Copy or download the XML.
How the markup is built
Every row becomes one element — <row> by default — inside a single wrapper element, because XML
documents need exactly one root. Each column becomes a child element named after its header, holding the cell
value. When the file has no header row, columns are named col1, col2 and so on.
Column names are made valid
Spreadsheet headers routinely look like First Name, 2026 Total or
Price (USD), none of which are legal XML element names — names cannot contain spaces or brackets and
cannot begin with a digit. Those characters are replaced with underscores and a leading digit gets an underscore
prefix, so the output always parses instead of failing when the receiving system reads it.
Common use cases
- Preparing a bulk import for a system whose API only accepts XML.
- Turning a spreadsheet export into an XML fixture for testing.
- Feeding tabular data into an older enterprise integration.
Frequently asked questions
How do I convert CSV to XML?
Paste your CSV or upload a .csv or .tsv file, set the delimiter if it is not a comma, and name the wrapper and row elements to match your target schema. The XML appears on the right, ready to copy or download.
How is the XML structured?
Every row becomes one element — called row by default — inside a single wrapper element, since XML requires exactly one root. Each column becomes a child element named after its header, holding the cell value.
What happens to column names with spaces or symbols?
Headers like First Name, 2026 Total or Price (USD) are not legal XML element names. Invalid characters are replaced with underscores and a leading digit gets an underscore prefix, so the document always parses instead of breaking downstream.
Can I choose the element names?
Yes. Both the wrapper element and the per-row element are configurable, so you can match whatever schema or import format you are feeding.
What if my CSV has no header row?
Uncheck the header option and columns are named col1, col2 and so on, so every row still converts to a valid element.
Is my CSV uploaded when I convert it?
No. Files you choose are read directly in your browser, so the contents never leave your device.
