Convert CSV to XML
Transform CSV into XML offline—parsed and serialized locally with zero backend processing.
Converting…
How it works
Converting CSV to XML is a two-step process that runs entirely in your browser. First, your CSV is parsed into a plain in-memory data structure. CSV rows become objects keyed by the header row. Nested values are flattened into dot-separated columns such as database.host and rebuilt on the way back; numbers and booleans are detected, while values with leading zeros stay text. Second, that structure is serialized as XML with consistent indentation, ready to paste into configs, APIs or scripts. XML elements become nested keys, attributes are kept with an @ prefix, repeated sibling elements become arrays, and the root element name is preserved. Because both steps are local JavaScript, sensitive payloads such as customer exports, infrastructure manifests and credentials files never travel to a server, and conversion keeps working on a flaky connection once the page has loaded. The output updates as you type, and invalid input is reported with the parser’s own error message so you can find the problem quickly. Spot-check important conversions, especially when your data mixes numbers that look like text, empty values and deeply nested arrays.
Frequently asked questions
Does converting CSV to XML upload my file?
No. Parsing and serialization happen entirely in your browser. PrivateDevTools has no conversion API.
What CSV shapes convert cleanly to XML?
Most structured documents convert cleanly. XML elements become nested keys, attributes are kept with an @ prefix, repeated sibling elements become arrays, and the root element name is preserved.
Will comments survive the conversion?
No. Comments are dropped when the input is parsed, so the output keeps your data but not your annotations.
Can I convert large documents?
Yes within browser memory limits. Extremely large files may feel slower on modest devices.
Is this available offline after first load?
Once the static page and scripts are cached by your browser, conversions continue without a network round trip for processing.
