Doesn't work. Can't open xlsx file, just keeps downloading but not opening. Very poor interface.

It wont get beyond the "Wait . . ." screen. It said that it would take less than 15 seconds. more than a minute is too long to wait

AI product read

Chrome extension that provides an online OpenOffice Calc spreadsheet editor for creating, editing, and viewing XLS/XLSX files, powered by the offidocs.com web service

Allows users to create, edit, and view Microsoft Excel (XLS/XLSX) spreadsheets directly in the browser without installing desktop software, with automatic detection of spreadsheet files on web pages

1. User installs extension and clicks the extension icon to open the popup UI. 2. The extension auto-generates a random anonymous username for backend session management. 3. User can click 'Files' to detect spreadsheet files on the current webpage. 4. User can click 'Run OOCalc' to launch the OpenOffice Calc editor (loaded via iframe from offidocs.com). 5. User can click 'File Manager' to access an elFinder-based file manager for uploading/downloading/managing XLS files. 6. User can click 'Full screen' to open the editor in a new full-width tab. 7. The extension also monitors browsing activity in the background (websecure.js) to detect spreadsheet files on visited pages.

Target users: Users who need to open or edit Excel spreadsheets without desktop software / Users who encounter XLS/XLSX files while browsing the web / Casual spreadsheet users who want a free browser-based editor

The extension relies entirely on the offidocs.com backend service; if that service changes or goes offline, the extension becomes non-functional
The elfinder.min.js is a large minified file (~138KB) — only the offidocs.com-related sections were inspected in detail
The offidocs.com backend may have its own account/subscription requirements not visible in the extension source code

Monetization

No paid features detected

No payment platforms, subscription checks, billing APIs, upgrade prompts, or premium feature gating found in the extension source. All 'pro' and 'license' keyword matches are false positives from third-party library headers (jQuery UI MIT/GPL license, elFinder BSD license) and CSS class names. The extension does not call any payment/subscription endpoints, does not display pricing tiers, and does not gate any features behind a paywall.

Confidence: 92
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension auto-generates a random anonymous 10-character username (popup.js line 20: username = "" + randomString(10) + "".toLowerCase()) and stores it in chrome.storage.local. There is no user-facing login UI, no password input, no OAuth flow, and no authentication step required. The 'loginx' div in index.html (line 91) is misleadingly named — it is initially hidden (display:none, line 61) and used to display the editor iframe, not a login screen. The auto-generated username serves only as an anonymous session identifier for the offidocs.com backend API.
