About CSV

Comma-Separated Values (CSV) files store tabular data with coordinate columns (latitude/longitude or WKT geometry). A simple, universal format supported by virtually all data tools.

Extensions: .csv
Software: Excel, Google Sheets, QGIS, Python/Pandas, R
Limitations: No built-in geometry type — requires coordinate columns. No CRS metadata. No support for complex geometries without WKT.

About XLSX

XLSX is the Microsoft Excel Open XML spreadsheet format. When it contains coordinate columns, it can be used as a source for geographic point data.

Extensions: .xlsx
Software: Microsoft Excel, Google Sheets, LibreOffice Calc, QGIS, Python/openpyxl
Limitations: No built-in geometry type — requires coordinate columns. No CRS metadata. Limited to tabular point data.
