The Scenario
You're a customer experience analyst. Three thousand open-ended survey responses came in from a global campaign — respondents wrote in whatever language felt natural. Before you can route them to the right regional team for follow-up, you need to know which language each response is in.
Your regional teams cover English, Spanish, French, German, and Portuguese. Anything else gets flagged for translation before routing. The responses need to be categorized and routed by end of day.
The bad version:
- Read each response and identify the language by eye — workable for 50, not 3,000.
- Write a formula that checks for common Spanish words like "es" and "de" — which returns false positives constantly because those are also English words.
- Export to a translation API that only offers language detection as a side feature of a translation call, paying per character for 3,000 responses you don't actually need translated.
The regional team leads are waiting. The routing delay is starting to back up their inboxes.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads your Google Sheet and calls Interzoid's language detection API for every response — writing language name and ISO code without you reading a single response.
For each text string in column B, use Interzoid to detect its language and write the language name and ISO code to columns C and D.
What You Get
- Column C: detected language name per response (e.g., Spanish, French, German).
- Column D: ISO 639-1 language code (es, fr, de).
- A dataset ready for routing — filter by column D to create per-language response batches for each regional team.
- Non-team-language responses flagged automatically for the translation step before routing.
What If the Data Is Not Quite Ready
Some responses are very short — one or two words — and detection may be unreliable
For each text in column B, check the character count first. If the response is fewer than 20 characters, write 'TOO SHORT' in column C and skip Interzoid. For longer responses, call Interzoid to detect the language and write the language name and ISO code to columns C and D.
You want to immediately create a filter showing only non-English responses
Identify the language of every comment in column A using Interzoid and write the detected language to column B, then add a filter showing only non-English responses.
You need confidence score as well to flag ambiguous detections
For each text in column B, call Interzoid's language detection tool and write the language name to column C, the ISO code to column D, and the detection confidence score to column E. Flag rows where the confidence score is below 70 as 'LOW CONFIDENCE' in column F.
Full classification + routing in one shot
For each response in column B: skip entries fewer than 20 characters (flag as 'TOO SHORT' in column C). For the rest, call Interzoid to detect the language and write the name to column C and ISO code to column D. Create five filtered output sheets — English, Spanish, French, German, Portuguese — each containing the relevant response rows. Put all other languages into an 'Other' sheet flagged for translation before routing.
The regional leads get their batches. The routing backlog clears.
