Native .xlsx on this server uses PHP only text extraction (upload vendor/ from local composer install). No system pdftotext on typical shared hosting. Max 80 pages, 25 MB.
Honest mode: Ye OCR nahi — sirf embedded text. Photos, logos, charts Excel cells mein picture ke roop mein nahi aate. Visual poora chahiye ho to PDF→PowerPoint (slide = page image) ya PDF→Word mein “page pictures” checkbox. PHP-only: columns approximate.
