Quality & Fidelity
File size after conversion depends on the content complexity and your quality settings. XML Document preserves all data losslessly, so output size depends on the content's inherent compressibility. Use JSON instead of XML for new web APIs — it's simpler For the best results, start with the highest quality Excel Spreadsheet source file available. XML Document is known for self-describing with schema validation, extensible for any domain. This means your converted output will benefit from XML Document's core strengths. Meanwhile, the original Excel Spreadsheet's advantage of powerful formulas, pivot tables, charts and data analysis capabilities may not fully carry over, depending on XML Document's capabilities.
