Modern Data Pipelines: Ingesting Excel Spreadsheets to JSON
While Microsoft Excel remains the dominant format for business analysis, accounting, and inventory tracking, modern cloud backends, NoSQL databases, and API frameworks require JSON. Converting spreadsheet rows into valid JSON objects bridges the gap between spreadsheet-driven operations and automated web software.
Supported Spreadsheet Formats
- Microsoft Excel (.xlsx): Standard XML-compressed spreadsheet format used by Excel 2007 through current Office 365.
- Legacy Excel (.xls): Binary format used by Excel 97-2003.
- OpenDocument (.ods): Standard format used by LibreOffice and open-source tools.
- CSV / TSV: Delimited text files.
