How the conversion works

Paste your XML on the left and press Convert. The tool first parses the XML (treating each child of the root element as a row, keeping attributes as @-prefixed columns) into an internal table of rows and columns, then writes it out as TOML (writing rows as an array of [[rows]] tables). If the input cannot be parsed you get a plain-English error instead of a broken file.

Where this comes in handy

People reach for this converter when pulling records out of XML feeds, sitemaps or API responses and TOML is needed for config files. Because everything runs locally in your browser, it is also handy for quick one-off migrations without installing database tools or writing throwaway scripts.

XML to TOML FAQs

What if my XML uses namespaces like ns:tag?
Namespaced tags are kept as-is for the column name, and any characters that are illegal in the target format are replaced with underscores.
Does it handle nested XML structures?
One level of nesting is flattened: every child element of the root becomes a row. Deeper structures are serialized as text inside their cell so nothing silently disappears.
What happens to nested values?
Nested objects and arrays that TOML cannot express natively are stored as JSON strings inside their cell.
How are table rows represented in TOML?
Each row becomes an entry in an array of tables ([[rows]]), with columns as keys inside each entry.
Is there a size limit?
No hard limit, but very large pastes (tens of megabytes) can slow down the browser tab. For huge inputs, split them into smaller chunks.
