Data conversion is the process of transforming data from one format to another while preserving the information and structure. Different applications and systems use different data formats, so conversion is essential for data exchange, integration, and compatibility. Our Data Converter handles the most common formats used in data processing and web development.
| Format | Description | Common Uses |
|---|---|---|
| CSV | Comma-Separated Values | Spreadsheets, databases, data analysis |
| JSON | JavaScript Object Notation | APIs, web applications, configuration files |
| XML | Extensible Markup Language | Data exchange, web services, configuration |
| TSV | Tab-Separated Values | Text processing, data exchange, databases |

Your data privacy is our top priority. When you upload a file to the Data Converter, all processing happens entirely in your web browser using JavaScript. No data is sent to our servers, stored in databases, or shared with third parties. The converted file is created locally on your device and downloaded directly to your Downloads folder. Once you close the browser tab, all data is immediately cleared from memory.
Q: What file formats can I convert?
A: You can convert between CSV, JSON, XML, and TSV formats. Upload CSV or JSON files and convert to any of the four supported formats.
Q: Is there a file size limit?
A: No! Data Converter can handle files of any size. All processing happens in your browser, so there are no server-side limitations.
Q: Will my data structure be preserved?
A: Yes, the converter maintains data integrity and structure during conversion. However, note that some formats (like JSON) support nested structures while others (like CSV) are flat, so complex nested data may be flattened.
Q: Can I convert XML or TSV to other formats?
A: Currently, you can upload CSV or JSON files and convert them to JSON, XML, TSV, or CSV. We're working on adding XML and TSV as input formats in a future update.
Q: How is JSON structured from CSV?
A: CSV data is converted to an array of JSON objects, where each row becomes an object and column headers become property names.
Q: Can I customize the output format?
A: The converter uses standard formatting for each output type. JSON is formatted with 2-space indentation for readability, XML includes proper tags and structure, and TSV/CSV use standard delimiters.
