JSON distribution of CLDR locale data for internationalization
It should be noted that XML (not JSON) is the "official" format for all CLDR data. The JSON data contained in the packages described below is provided as a convenience for the development community, and is programatically generated from the corresponding XML, using the JSON conversion utility that is provided as part of the CLDR tooling (written in Java).
The data in these packages is intended to serve as a common reference point for most
draft="approved" status in the CLDR. This is the same threshhold
as is used by the ICU (International Components for Unicode).
If you require JSON data containing provisional or unconfirmed data, or data that is customized
in any way, you can generate it using the Ldml2JSON conversion utility in CLDR's tools
Latest official release is version 37.0.0, published on 2020-04-23
Each repository is tagged with the release it pertains to, for example
This project requires the following other projects to run:
Because the CLDR is so large and contains so many different types of information, the JSON data here is grouped into packages by functionality. For each type of functionality, there are two available packages: The "modern" packages, which contain the set of locales listed as modern coverage targets by the CLDR subcomittee, and the "full" packages, which contain the complete set of locales, including those in the corresponding modern packages. The functional groups are:
- cldr-core – Basic CLDR supplemental data — only one package here, no "full" and "modern".
- cldr-dates – Data for date/time formatting, including data for Gregorian calendar. Requires that the corresponding cldr-numbers package be installed as well.
- cldr-cal-[type] – CLDR data for non-Gregorian calendars. [type] is one of the supported non-Gregorian calendar types in CLDR: buddhist, chinese, coptic, dangi, ethiopic, hebrew, indian, islamic, japanese, persian, or roc.
- cldr-localenames – Translated versions of locale display name elements: languages, scripts, territories, and variants.
- cldr-misc – Other CLDR data not defined elsewhere.
- cldr-numbers – Data for number formatting.
- cldr-rbnf – Rule Based Number Formatting data — only one package here, no "full" and "modern".
- cldr-segments – Line breaking data from Unicode's ULI project
- cldr-units – Data for units formatting.
