Drop PROPERTIES files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the JSON, or download everything as one ZIP if you converted several files.
The PROPERTIES to JSON converter is part of this page and runs inside your browser. Your configuration files are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
PROPERTIES is flat, with no nesting or data types, and non-Latin text is stored as escapes. JSON is what APIs and most programming languages read natively. PROPERTIES is at home in configuration and translations in Java applications; JSON is the usual choice for APIs and data exchanged between programs.
Comment lines, the three separators (=, : or a space), continued lines and \uXXXX escapes are understood. A file that is valid UTF-8 is read as UTF-8, otherwise as Windows-1252. Every value stays text.
A .properties file is a list of key=value lines read by Java's Properties class. It is also the format for translation strings in Java applications. Traditionally the file is read as ISO 8859-1, so characters outside Latin-1 appear as \uXXXX escapes.

PROPERTIES converterJSON represents data as nested objects and lists in plain text. It is the default language of web APIs. Unlike a spreadsheet it can be nested to any depth, which is also why turning it into rows and columns takes a decision about how to flatten it.

No. The PROPERTIES to JSON conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
The values are kept. Anything JSON has no way to express, such as formatting, formulas or nesting, is simplified or left out.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the PROPERTIES file, press Convert and save the JSON. There is nothing to install.
Yes. Data files up to 300 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
