Data Utility
Format Conversion
Turn a flat CSV into a simple XML document (one element per row, one child tag per column), or flatten record-style XML back into CSV columns. Values stay as text, so leading zeros and ID codes survive the round trip.
- CSV to XML (row and column elements)
- XML to CSV (auto-unioned columns)
- Leading-zero safe by default
Need deeply nested XML or real transformation?
A flat swap is step one. To map data into a specific nested XML schema, reshape records, apply business logic, or validate every row before import, you need a dedicated transformation engine, not a converter.
Client-Side Processing ArchitectureSecure
Your data never leaves your device. All processing happens locally in your browser's memory via WebAssembly/JavaScript. This ensures complete data sovereignty and compliance with GDPR, HIPAA, and SOC2 standards as no files are uploaded to our servers.
Frequently Asked Questions
How do I convert CSV to XML?▼
Paste or upload a CSV whose first row is the header. The tool wraps the file in a <rows> root and writes one <row> element per record, with one child tag per column. Click the CSV/XML toggle to convert in the other direction.
What XML structure does it produce?▼
A simple, standard record structure: an XML declaration, a <rows> root, a <row> element per data row, and a child element named after each column. Column names are sanitized into valid XML tag names (spaces and symbols become underscores).
Will it preserve leading zeros and long ID numbers?▼
Yes. Every value is written as text, so leading zeros, ZIP codes, and account numbers are never reformatted or turned into numbers.
Can it convert XML back to CSV?▼
Yes, it is fully two-way. Each direct child of the root element becomes a row, its child tags become columns, and the columns are unioned across all records so nothing is dropped when rows differ.
Is my data secure?▼
Yes. Conversion runs 100% in your browser. Your file is processed locally in memory and is never uploaded to our servers.
