Viewing office documents online on the site?

Question

Data conversion

The customer requires to organize the viewing of downloaded documents - online.
doc\docx, xls\xlsx,ppt\pptx, pdf formats
I thought to myself that I would do it calmly on docs.google.com/viewer
but the customer sent me a 100 MB presentation, a huge xlsx with several sheets and the same docx.
and because of the limits - support.google.com/drive/bin/answer.py?hl=en&answe... not one such document was opened (I was especially surprised by the limit on word files - 2mb)
I appeal to those who solved this problem - what means were used?
Any options that can solve the problem are considered: from console converter utilities to paid third-party services.

Answer 1

Have you tried SkyDrive?

Answer 2

Convert the presentation to video, embed it in the website. XLSX and DOCX to PDF.

Answer 3

Office Web Viewer
officewebviewer.com

Answer 4

Look aside www.zoho.com
True, they don’t know how they are with the limits now.

Answer 5

I had such a task, but only PDF was required there. I was just opening PDFs inside an IFRAME. Browsers either rendered it themselves, or launched an adobe plugin.
Maybe automate the resaving of all PDF files? Via Microsoft Office or Libre Office.
