Frequently Asked Questions (FAQs)
Excel parsing and analysis is the process of extracting, examining, and understanding the structure, content, and properties of Excel files. It goes beyond simple conversion to provide deep insights into data types, formulas, formatting, hidden elements, and overall workbook structure.
The parser extracts comprehensive information including: sheet dimensions and ranges, cell statistics (total, empty, formulas, formatted), data type distribution, formula analysis, hidden rows and columns, merged cells, formatting styles, column and row analysis, and detailed structural metadata.
The parser identifies all cells containing formulas, extracts the formula text, calculates current values, and categorizes them. You can search and filter formulas by cell address or formula content, making it easy to audit complex spreadsheets and understand calculation dependencies.
Yes, the parser is optimized to handle files up to 100MB. It processes files efficiently in the browser without uploading to servers. For very large files, the analysis focuses on key structural elements while providing representative samples of data content.
The parser supports all major Excel formats: .xls (Excel 97-2003), .xlsx (Excel 2007+), .xlsm (macro-enabled), .xlsb (binary), and .ods (OpenDocument). It can handle multiple sheets, complex formulas, and various data types across different Excel versions.
All parsing and analysis happens entirely in your browser. Your Excel files are never uploaded to any server - they stay on your computer throughout the analysis process. This ensures complete privacy and security for sensitive business data.
Common use cases include: data quality assessment, spreadsheet auditing, formula debugging, data migration planning, understanding complex workbooks, documentation generation, data governance, and preparing for system integrations or database imports.
Yes, the parser provides both workbook-level overview and detailed sheet-by-sheet analysis. You can navigate between sheets, compare their structures, and get aggregated statistics across the entire workbook while maintaining the ability to drill down into individual sheet details.
