CSV/JSON/XML Converter

Convert between CSV, JSON and XML formats

CSV/JSON/XML Converter is a universal tool for converting data between CSV, JSON, and XML formats in any direction. Supports all 6 conversion types: CSV ↔ JSON, CSV ↔ XML, JSON ↔ XML. The tool automatically detects CSV delimiters, handles headers, parses XML structures, and properly formats output data. Useful for working with data, importing/exporting tables, converting XML catalogs, and integrating various systems.

CSV/JSON/XML Converter: Universal Data Conversion

🔄 CSV/JSON/XML Converter: Free Online Tool for Data Conversion

CSV/JSON/XML Converter is a universal tool for converting data between three popular formats: CSV (Comma-Separated Values), JSON (JavaScript Object Notation), and XML (eXtensible Markup Language). The tool supports all 6 conversion types in any direction.

📊 Supported Formats

CSV (Comma-Separated Values) — a text format where each line represents a record, and values are separated by commas (or other delimiters). CSV is widely used in tables, databases, and spreadsheets.

JSON (JavaScript Object Notation) — a JavaScript-based data format widely used in web development, APIs, and configuration files. Supports nested objects and arrays.

XML (eXtensible Markup Language) — a markup language for storing and transmitting structured data. XML is widely used in web development, configuration files, APIs, and data exchange between systems.

🔄 Conversion Types

The tool supports all possible conversions between formats:

  • CSV → JSON: Convert tabular data to structured JSON
  • JSON → CSV: Convert JSON arrays to CSV table format
  • CSV → XML: Convert CSV to XML structure
  • XML → CSV: Extract data from XML and convert to CSV
  • JSON → XML: Convert JSON objects to XML format
  • XML → JSON: Parse XML and convert to JSON structure

✨ Tool Features

  • Universal: Support for all conversions between CSV, JSON, and XML
  • Automatic delimiter detection: Support for commas, semicolons, and tabs for CSV
  • Header handling: Automatic use of first row as column headers
  • Pretty formatting: Readable JSON and XML output with indentation
  • XML parsing: Smart extraction of data from complex XML structures
  • Security: All data is processed locally in your browser

💡 Use Cases

  • Data import: Convert CSV to JSON for use in web applications
  • Data export: Convert JSON to CSV for work in Excel or other spreadsheet editors
  • XML catalog conversion: Convert XML catalogs (e.g., CD catalogs) to CSV or JSON
  • Data migration: Transfer data between systems with different formats
  • API integration: Prepare data for REST API in the required format
  • Configuration processing: Convert configuration files between formats

🔧 Technical Details

  • CSV processing: Uses PapaParse library for CSV parsing and generation
  • JSON processing: Uses built-in JSON.parse and JSON.stringify
  • XML processing: Uses fast-xml-parser library for XML parsing and generation
  • Formatting: Automatic indentation and line breaks
  • Escaping: Correct handling of special characters in XML

Intro

A data converter transforms structured data from one format into another. Common conversions include JSON to CSV, CSV to JSON, XML to JSON, YAML to JSON, or similar mappings between formats used by APIs, spreadsheets, scripts, and configuration files. This is useful when data needs to move between systems that expect different structures.

For example, an API may return JSON, but a stakeholder wants a CSV file for Excel. A legacy export may come as XML, while a modern tool expects JSON. Instead of rewriting fields by hand, a data converter maps the input into the target format much faster and with fewer mistakes. It can save significant time during reporting, migration, testing, and integration work.

The main value of this tool is consistency. Manual conversion often breaks escaping, nesting, separators, or data types. A proper converter handles the structural rules automatically, making the output easier to trust and reuse.

How to Use

1. Paste or upload the source data in its current format. 2. Choose the target format, such as JSON, CSV, XML, or YAML. 3. Run the conversion, review the output, and copy or download the result.

Examples

  • Input JSON: [{"name":"Ana","age":30}]

Output CSV: name,age then Ana,30

  • Input CSV: name,age / Luis,25

Output JSON: [{"name":"Luis","age":"25"}]

  • Input XML: 7

Output JSON: {"user":{"id":"7"}}

Tips

  • Check whether numbers and dates should stay as strings or typed values.
  • Review nested data carefully when converting to flat formats like CSV.
  • Validate the output before importing it into production systems.

FAQ

Can every format convert perfectly to every other format?

Not always. Some formats support nesting and metadata that flatter formats cannot preserve fully.

Why do numbers sometimes become strings?

Because some formats, especially CSV, do not carry strict type information.

Should I review the output manually?

Yes. Even when the conversion succeeds, it is wise to check headers, delimiters, and nested fields before using the result.
