Spreadsheet Splitter

Welcome to the Spreadsheet Splitter Knowledge Base!

In this comprehensive resource you will find everything you need to know about dividing a single spreadsheet into many separate files quickly, accurately, and with confidence. Whether you are an analyst, a developer, or an everyday user looking to break down large workbooks into manageable pieces, our platform empowers you to split Excel files while preserving formulas, formatting, macros, and embedded objects. The knowledge base is organized into clear sections that guide you step‑by‑step through every stage of the splitting process, from selecting the source file to configuring advanced options for handling complex workbooks.

Our splitting engine is built to support a flexible and symmetric workflow: both the input and the output can be any of the supported formats.

This means you can start with an Xlsx file and generate multiple Xlsb, Xltm, Xlam, Excel97To2003, Excel95, SpreadsheetML, or Xlt files, and you can also split legacy documents into modern, feature‑rich formats. The supported formats include:

• Xlsx – the standard Office Open XML workbook format for Excel 2007 and later.
• Xlsb – the binary workbook format offering faster opening and saving for large files.
• Xlsm – workbooks that contain macros, preserving VBA code during splitting.
• Xltm – macro‑enabled template files, useful for reusable spreadsheet templates.
• Xlam – add‑in files that extend Excel’s functionality with custom functions.
• Excel97To2003 – the classic binary .xls format used in Excel 97 through 2003.
• Excel95 – the early Excel format, still supported for legacy data migration.
• SpreadsheetML – the XML representation of spreadsheets, ideal for web‑based processing.
• Xlt – standard Excel template files for creating new workbooks with predefined layouts. Because the splitting respects the full feature set of each format, you can trust that formulas, pivot tables, charts, conditional formatting, data validation, and even custom VBA macros will remain intact in every output file. Detailed articles walk you through common scenarios, such as splitting a master workbook into one file per worksheet, extracting a range of rows into separate files, or batch‑splitting a folder of Xls files into individual Xlsx workbooks for downstream analysis.

If you encounter a specific challenge—perhaps a macro that behaves differently after splitting, or a need to preserve external data connections—our knowledge base provides troubleshooting guides, best‑practice recommendations, and examples of how to use our advanced options (e.g., preserving macro signatures, handling hidden sheets, or customizing XML namespaces for SpreadsheetML).

Each guide includes screenshots, code snippets, and downloadable sample files so you can experiment safely before applying changes to production data.

Finally, we understand that security and privacy are paramount when handling sensitive spreadsheets.

All splitting operations are performed locally in your browser or on your trusted server environment, ensuring that your data never leaves your control unless you explicitly choose to share it. The knowledge base also outlines how to configure secure endpoints, manage authentication tokens, and audit splitting logs for compliance purposes.
