Free Data Tools for CSV, JSON, XML & Excel

Convert and transform CSV, JSON, XML, Excel, and other supported data formats online.

Move Data Between Common Formats

Use a format-pair tool such as CSV to JSON, Excel to XML, or JSON to XML. Tabular and nested formats represent data differently, so inspect headers, types, empty values, and nesting in the result.

βœ“ Format-Specific Tools

Choose a specific source-and-target pair so parsing rules match the formats you are working with.

βœ“ No Installation

Open the tools through a modern web browser without installing separate conversion software. Browser and device behavior can vary by file type, size, and selected tool.

βœ“ Processing Time Varies

Conversion time depends on input size and structure. Inspect the result before replacing a source dataset.

βœ“ Server-Side Processing

Input is sent over HTTPS to the conversion service. Remove credentials and sensitive records before submitting data.

Check the Structure After Conversion

Select the format-pair tool you needβ€”for example, CSV to JSON or Excel to CSV. Provide the supported input, start the conversion, and use the available download or copy option when processing finishes. Check headers, field types, delimiters, empty values, and nested structures before relying on the converted data.
