SXC Viewer Online

This tool renders a read-only preview of legacy SXC spreadsheets in a web browser. It is designed for data archivists, IT teams, and analysts who need to quickly inspect file contents without desktop software. The service reads SXC file structure, reconstructs sheet grids, and presents a faithful visual representation of cells and basic formatting. It also exposes a data snapshot that can be exported for migration or auditing tasks. Conceptually, the tool operates as a specialized parser and renderer: it parses the binary or structured SXC format, normalizes cell values, and then produces either a PNG or SVG preview alongside a structured data export. The value lies in enabling rapid data discovery, integrity checks, and lightweight data extraction from legacy formats, reducing time-to-insight in archival workflows. Core features include file upload or URL input, sheet selection, a rendered preview, and optional exports to CSV or JSON. Use cases include pre-migration validation, content auditing, and archival documentation. Unique differentiators are the strict read-only posture, support for UTF-8 content, multi-sheet previews, and the ability to export data without editing the source file. The tool targets teams that manage legacy data repositories and require a dependable, browser-based viewing solution that does not depend on specialized desktop software.
