Convert XML, CSV, and TSV files to formatted JSON in your browser
Select or drag and drop XML, CSV, or TSV files to convert
Converts XML elements to nested JSON objects with attributes preserved
Parses comma-separated values into JSON array with automatic type detection
Handles tab-separated values with robust parsing and error handling
Use this file to JSON converter online when you need to turn XML, CSV, or TSV files into clean JSON without installing software. It is built for API testing, spreadsheet exports, data migration, configuration cleanup, and quick developer workflows where the first useful result should be a downloadable `.json` file.
The converter reads your selected files in the browser, parses the source format, previews formatted JSON, and lets you download one JSON file per successful conversion. It focuses on the most common file-to-JSON jobs:
Using our converter is incredibly straightforward. Since all processing happens in your browser, your sensitive data never touches our servers. Follow these steps to convert your data:
This tool uses browser APIs to read and convert files locally. The conversion does not require a server upload from this page, which is useful when you are checking API payloads, customer exports, inventory spreadsheets, or private configuration files.
Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents. Converting XML to JSON can be tricky due to attributes and nested identical nodes. Our parser intelligently handles this by:
Comma-Separated Values (CSV) is the most common export format for spreadsheets and relational databases. Our CSV to JSON engine provides:
Tab-Separated Values (TSV) are often preferred over CSV when the dataset contains commas within the data fields (like addresses or text descriptions). The parsing engine handles TSV files with the same robust dynamic typing and header detection as CSVs, simply using the tab character (`\t`) as the delimiter.
Converting static legacy XML configuration files or data exports into JSON for use in modern React, Vue, or Angular frontend applications.
Exporting relational database tables as CSV, converting them to JSON arrays, and importing them directly into NoSQL databases like MongoDB.
Transforming spreadsheet data from analysts into structured JSON for ingestion into Python pandas DataFrames or machine learning pipelines.
Taking XML responses from older SOAP APIs, converting them to JSON, and passing them along to modern RESTful microservices.
Yes, our File to JSON Converter is 100% free with no hidden fees, no subscription requirements, and no daily usage limits. You can convert as many files as you need.
The converter reads and processes files in your browser from this page. It does not need to upload XML, CSV, or TSV files to a server to create the JSON output.
When an XML node contains attributes, the converter creates a special `@attributes` object inside the resulting JSON object to store them, ensuring no metadata is lost during the transformation. If the node also contains text, it is stored under a `#text` key.
Yes! You can highlight and upload multiple files at once using the file picker, or drag and drop a batch of files. The tool will process them in sequence and provide individual download links for each converted JSON file.
Yes, our CSV engine features dynamic typing. This means if a column contains 'true', 'false', or numerical values like '42.5', they will be output as native JSON booleans and numbers, rather than strings wrapped in quotes.
Because the processing happens in your browser, the file size limit depends entirely on your device's available RAM and browser capabilities. Generally, files up to 50MB process smoothly, but massive gigabyte-scale datasets might cause browser lag. If you experience issues with large files, try splitting them into smaller chunks.
