About XLSX
XLSX is Microsoft Excel's spreadsheet format, storing rows, columns, formulas, and formatting in a compressed XML archive.
The standard choice for budgets, data tables, and anything requiring formulas or multiple sheets.
A single XLSX sheet can hold over 1 million rows and more than 16,000 columns.
💡 Excel's grid limit was only 65,536 rows until 2007. The modern 1,048,576-row limit is exactly 2^20.
About JSON
JSON (JavaScript Object Notation) is a lightweight, human-readable format for structuring data as key-value pairs and lists.
The default format for APIs, configuration files, and passing structured data between web applications.
JSON was specified by Douglas Crockford in the early 2000s and is now defined by RFC 8259.
💡 Despite "JavaScript" in its name, JSON is language-independent and used by virtually every modern programming language.
