Data Converter Convert JSON, XML, CSV, Excel, PDF, JPG, PNG and WebP files online for free. No registration or software installation required.
Our tools help developers, analysts, testers, students, and businesses convert data between multiple formats quickly and securely.
Most converters expect perfectly formed input. In practice, data rarely arrives that way — it's copied from Slack, pasted from an API response, exported from a legacy system, or typed by hand. Here's what happens to it before anything gets converted.
Single quotes instead of double quotes, missing quotes around keys, trailing commas, and smart quotes copied from Word or Google Docs are all fixed before parsing — paste data as-is instead of cleaning it up first.
Pasted data that looks like rows and columns — an array of arrays — is converted into proper records automatically, using the first row as column headers.
Paste a full API response and the converter finds the actual list of records inside it, even nested inside a "data" or "results" wrapper. If more than one list is found, you're shown each option with a record count so you can pick the right one.
XML pasted without a single wrapping root — or with several different repeating elements, like both Orders and Customers — is repaired automatically or presented as a choice, instead of failing outright.
Converting between JSON and XML keeps nested objects and arrays intact — nested fields stay nested, repeated fields become repeated elements. Converting to Excel or CSV, which can't represent nesting, flattens nested fields into columns like "address.city" automatically.
