About This Tool

This tool renders Excel workbooks in a read-only preview across sheets, preserving row and column organization for quick validation and review. It supports standard file uploads, per-sheet navigation, and data export to CSV. The rendering focuses on accurate values and structure rather than editing, making it suitable for auditors, managers, and collaborators who need a reliable snapshot of workbook content. Conceptually, the workflow treats the workbook as a collection of grids that are parsed, validated, and presented in a consistent, non-destructive format. The system emphasizes deterministic rendering, locale-aware formatting hints, and safe handling of formulas by displaying calculated values when possible. Unique value lies in not requiring Excel installation while delivering faithful previews and lightweight exports. Core features include multi-sheet previews, read-only rendering, and CSV export; use cases include data verification, shareable reviews, and lightweight data extraction for reporting.

Frequently Asked Questions

Find Quick Answers

What file types are supported?

Supported formats include xlsx and xls. Large files may be limited by size constraints; macros are not executed and the view is read-only. The tool focuses on accurate rendering of data and structure, not on editing capabilities.

Can I export to CSV?

Yes. You can export the currently viewed sheet to CSV with proper escaping. The CSV reflects the rendered grid values, including headers, and preserves basic formatting as text where applicable.

Are macros executed?

No. The viewer does not execute macros or perform macro-driven calculations. It displays the resulting values and structure that are available in the workbook without editing.

How is data handled and is it private?

Uploads are processed for the duration of the session and may be stored temporarily by the service. The viewer is read-only, and exported data is provided as downloadable files. Users should avoid uploading sensitive data if retention policies apply.
