What KIVO checks

PDF: Structure, page count, encryption and truncation damage.
JSON: Syntax errors — and automatic repair of trailing commas, comments, single quotes and BOMs.
CSV: Delimiter detection, ragged rows, duplicate headers, byte-order marks.
Images: Decodability, dimensions, and the HEIC compatibility trap.
Any file: Real format from its signature, so a mislabelled extension gets caught.

Frequently asked questions

Why does my file open on one computer but not another?: Usually the extension doesn't match the real format, or it's a HEIC photo. KIVO checks the file's actual signature, so it catches both.
Can KIVO recover a badly corrupted file?: Sometimes. Structural JSON and CSV problems are often repairable. A truncated PDF or image is genuinely missing data — no tool can invent it back.
