Convert CSV to XML

Wrap each CSV row in an XML element using your chosen root and row tag names. Special characters are entity-escaped automatically so the output is well-formed.

Quick Start

How CSV becomes XML

Headers turn into element names — make sure they're valid XML identifiers. Each remaining row wraps in your chosen row tag, and the whole document sits under a configurable root.

  1. 01

    Set tag names

    Root wraps the whole document; row wraps each record. Defaults are rows and row.

    Parsing is strict-but-tolerant — comments and trailing commas are accepted on input where the source format historically permits them; output stays canonical.

  2. 02

    Paste CSV

    First row defines the column names — and therefore the child element names.

    Conversion preserves type information where the target supports it (numbers stay numeric, booleans stay boolean) so the destination parser never has to re-coerce.

    Entities escaped

    Ampersands, less-than and greater-than signs are escaped so the output stays well-formed.

    Re-encoding is idempotent: running output back through the same converter produces the same bytes, which keeps round-trips git-friendly.

    Copy or download

    Save as .xml — ready for SOAP services, RSS, legacy ETL pipelines.

    Copy writes via navigator.clipboard.writeText; downloads use the target’s native MIME so editors apply the right syntax highlighting on open.

Pro tips

Converting between formats, safely

Pick the strictest source format

Lossy formats hide bugs. Choose JSON or YAML as your source-of-truth, convert downstream as needed.

Round-trip in CI

If your converter is idempotent, your CI can verify A → B → A equals the original. Catches subtle data loss.

Numbers vs strings differ

YAML/TOML have a number type; CSV doesn’t. Quote IDs in CSV to keep leading-zero values intact.

Watch character encoding

Source format may be Latin-1 / Windows-1252; target should be UTF-8. Convert encoding before structure.

Preserve comments where you can

YAML and TOML support comments. Don’t silently drop them — they often encode intent.

Schema-aware beats blind

Use a schema to guide conversion. Field types, required-ness, and defaults survive better with structure.

Use Cases

When to convert CSV to XML

Legacy systems, exports, SOAP requests.

SOAP payloads

Build XML request bodies from spreadsheet test fixtures. Type information survives: numbers stay numeric, booleans stay boolean, strings stay strings. The destination parser doesn't have to re-coerce, which avoids the &quot;'true' becomes &quot;true&quot;&quot; bug class.

round-trip safe

RSS bootstrap

Seed an RSS / Atom feed from a CSV content calendar. Run output back through the inverse converter to verify idempotent round-trips in CI. A → B → A should produce byte-identical input — if it doesn't, you've found data loss.

type-preserving

Legacy ETL

Hand XML to systems that no longer accept CSV. Comments and metadata survive where the target format supports them (YAML, TOML, HCL). The tool doesn't silently drop intent-encoded annotations, which keeps your config self-documenting.

schema-aware

Fixture data

Generate XML fixtures for snapshot tests. Pair with a schema (JSON Schema, OpenAPI, Zod, Pydantic) to catch shape drift on either side. Catch breaking changes at conversion time rather than at runtime in production.

lossless

Government feeds

Many open-data feeds require XML uploads. Output respects target-format conventions: quoting in CSV, indent in YAML, brackets in JSON. Existing parsers don't need patches, and the result drops into legacy pipelines unchanged.

diff-clean

B2B integrations

Trading-partner integrations often demand XML. Encoding-aware: handles UTF-8 vs UTF-16 vs Latin-1 / Windows-1252 transparently. The character-set surprise that breaks &quot;works on my machine&quot; doesn't apply here.

FAQ

Frequently asked questions

No — make sure your CSV headers are valid XML names (letters, digits, hyphens, underscores, no spaces).
All values render as child elements. Attribute output isn't currently supported.
Ampersand, less-than and greater-than are escaped automatically.
Add them manually in the root tag input (for example rows xmlns="https://example.com/ns").
No. The conversion runs entirely in your browser.
