Switch helps you add multiple languages to your site by leveraging the power of google spreadsheets. It is a commandline tool providing you with an easy way to automate the process and avoid common mistakes.
The most common use case of switch is for switching between a locale representation in JSON/YAML to a CSV (spreadsheet) based one and vice-versa.
gem install switch-cli
switch json2csv [input-dir] [output-file]
Converts multiple json files to be a single csv file with columns for each file, with the file name as the column header.
If you do not specify an input-dir it will be taken as ./locales and output-file would be the direcotry name + .csv.
switch csv2json [input-file] [output-dir]
Converts a single csv file into multiple json files, with a file for each column using the key and order columns to construct the files.
