Jev interpretation

AI receives a reduced JSON sample (at most five items per array) and your instructions. Your inputs are not stored by this application or sent to analytics. TypeSafe receives submitted AI context.

I agree to send this context to Jev.

I reviewed the selected record array and nested-array policy.

What this tool does

Select the record array before exporting. Nested objects become dot-separated columns. Other arrays must be explicitly rejected, omitted, or stored in one JSON-text cell. This version does not explode nested arrays or join parent context automatically. Formula-like cells are escaped before spreadsheet import.

Privacy and uncertainty

Only explicit AI requests send bounded source context to Jev through our protected server. There is no account or application input-history database. AI classifications can be wrong; typed output is not proof of truth. Read privacy and operating limits.
