Why test with Arabic and Hindi text, not only English?

Because most of what breaks with non-Latin text never shows with English. Arabic runs right-to-left and mixes with left-to-right numbers and code, its letters change shape by position, and it carries optional diacritics that make two "equal" strings unequal; Hindi's Devanagari joins consonants and vowel signs into clusters that a character counter, a truncation or a cursor can split wrongly. Locale formats differ too — Eastern Arabic digits, the Hijri calendar, Indian number grouping (1,00,000). A suite with only English data leaves all of this untested.

Frequently asked questions about Multilingual Test Data Generator

Which languages are available?

English, Arabic, Hindi, French, German, Spanish, Chinese (Simplified), Japanese, Russian, Turkish and Urdu — spanning Latin, Arabic, Devanagari, CJK and Cyrillic scripts and both text directions.

What is the difference between long and wide shape?

Long gives one row per record and language (good for translation tables); wide gives one row per record with a column per language (good for spreadsheets and side-by-side review).

What is the welcome field?

A localised "Welcome back, {name}!" with a name interpolated in the language's script — the classic i18n interpolation case where punctuation and word order differ.

Are names and cities localised in every language?

Only English, Arabic and Hindi rows get a native-script name (and, in long shape, a local US, Saudi or Indian city). French, German, Spanish, Chinese, Japanese, Russian, Turkish and Urdu rows keep the English name and city while product, sentence and welcome message are translated — a realistic mixed-script case. Within a record the product is the same item everywhere.
