CSV To XML

What is CSV to XML Conversion?

CSV is a flat file format used to store data in rows and columns, while XML is a hierarchical format designed for structured data interchange. Converting CSV to XML allows you to wrap flat data with semantic tags—ideal for XML parsers, testing pipelines, and data interoperability.

Example 1: Basic User Data

CSV Input

id,name,email
101,Alice,alice@example.com
102,Bob,bob@example.com

Generated XML

<root>
  <row>
    <id>101</id>
    <name>Alice</name>
    <email>alice@example.com</email>
  </row>
  <row>
    <id>102</id>
    <name>Bob</name>
    <email>bob@example.com</email>
  </row>
</root>

You can use CSV to JSON to convert the same data to a structured JSON format.

Example 2: Product Catalog

CSV Input

product_id,product_name,price,currency
001,Wireless Mouse,25.99,USD
002,Gaming Keyboard,89.50,USD

Generated XML

<root>
  <row>
    <product_id>001</product_id>
    <product_name>Wireless Mouse</product_name>
    <price>25.99</price>
    <currency>USD</currency>
  </row>
  <row>
    <product_id>002</product_id>
    <product_name>Gaming Keyboard</product_name>
    <price>89.50</price>
    <currency>USD</currency>
  </row>
</root>

Want to test prices later? Convert to CSV to YAML and use YAML for readable config files.

Example 3: Handling Empty Values

CSV Input

username,email,phone
john_doe,john@example.com,
jane_doe,,+1555123456

Generated XML

<root>
  <row>
    <username>john_doe</username>
    <email>john@example.com</email>
    <phone></phone>
  </row>
  <row>
    <username>jane_doe</username>
    <email></email>
    <phone>+1555123456</phone>
  </row>
</root>

Empty values are preserved as empty XML tags. This is useful for APIs or backend systems expecting keys even if values are missing.

Example 4: Multiline Address or Notes (Escaped Properly)

CSV Input

user_id,name,note
1,Alice,"Hello, this is a note
that spans multiple lines."
2,Bob,"Another note with
line breaks and commas, too

Generated XML

<root>
  <row>
    <user_id>1</user_id>
    <name>Alice</name>
    <note>Hello, this is a note
that spans multiple lines.</note>
  </row>
  <row>
    <user_id>2</user_id>
    <name>Bob</name>
    <note>Another note with
line breaks and commas, too.</note>
  </row>
</root>

Multiline or special characters are handled correctly. To convert these notes into YAML format, try CSV to YAML.

Example 5: Date/Time with Mixed Data

CSV Input

event_id,title,date,is_active
001,Launch Event,2024-08-15,true
002,Backup Test,2024-09-01,false

Generated XML

<root>
  <row>
    <event_id>001</event_id>
    <title>Launch Event</title>
    <date>2024-08-15</date>
    <is_active>true</is_active>
  </row>
  <row>
    <event_id>002</event_id>
    <title>Backup Test</title>
    <date>2024-09-01</date>
    <is_active>false</is_active>
  </row>
</root>

This format is useful for automating XML-based event logs. You can cross-check date patterns using the Date Regex Python Validator.

How It Works

1. Upload a .csv file or paste CSV data into the input box

2. Click Convert to XML

3. The tool generates clean, valid XML that you can copy or download instantly

All processing happens in your browser—your data never leaves your device.

Use Cases

• Data Migration: Move data from spreadsheets into XML for legacy systems

• API Testing: Prepare XML payloads for testing SOAP-based or REST APIs

• Data Cleaning: Convert and format user data for database insertion

• Integration: Convert CSV exports from CRM/ERP into XML for third-party tools

• Use CSV to JSON or CSV to YAML for multi-format compatibility

• Follow up with XML to YAML or XML to JSON if needed downstream

Pro Tips

• ✅ Make sure the CSV includes a header row. It’s used as XML tag names

• 🧾 Avoid empty rows or malformed CSV—these may cause structural errors in XML

• 🔍 All values are treated as strings in XML. Wrap numeric data in quotes if needed

• 📁 Always test round-trip conversions using XML to CSV for accuracy

• 🔐 Your data is processed entirely client-side—perfect for secure or sensitive use cases
