# JSON file "null" to empty string converter

# For use with WebTranslateIt and Google Chrome extension i18n files
# -WTI will spit out unproofread segments as "null" (without quotes), but
# Chrome needs missing segments to be empty strings
# -Replace "null" with an empty string so that the target files can still be
# properly marked as unproofread in the WTI UI
