How to Merge XLSX Spreadsheets Using Python REST API

Combining several Excel workbooks into a single file can quickly become a headache when you have to preserve each sheet's data, formatting, and formulas across different versions. In Python projects the usual file‑system tricks or local libraries often stumble on large files, mismatched column types, or the need to stream data without loading everything into memory. These pain points make a reliable, server‑side merge essential for any automation pipeline. The GroupDocs.Merger Cloud SDK for Python offers a REST‑based solution that tackles Excel merging head‑on, letting you upload workbooks, specify merge order, and receive a consolidated spreadsheet without worrying about local resource limits.
