What is a Excel (XLSX) file?

XLSX is the Excel workbook format introduced with Office 2007. It stores one or more worksheets of cells with values, formulas, formatting, charts and defined names in a ZIP of XML parts. Formulas are recalculated by the program that opens the file.

Strengths

  • Keeps formulas, number formats, multiple sheets and charts
  • Opens in Excel, LibreOffice Calc, Google Sheets and Numbers
  • Handles large tables (over a million rows per sheet)

Limitations

  • Printed layout depends on page setup and can split tables awkwardly
  • Macros require the separate .xlsm format
  • Not human-readable without a spreadsheet program

Typical uses: Budgets, financial models and data analysis; Lists and tables that will be sorted or filtered; Source data for charts and reports.

What is a JSON file?

JSON is a lightweight text format for structured data: objects of key-value pairs, arrays, strings, numbers and booleans. It is the standard format for web APIs and configuration and is read natively by every modern programming language.

Strengths

  • Nested structure, not just flat tables
  • Native to JavaScript and web APIs
  • Easy for programs to read and validate

Limitations

  • Not meant for humans to read at length
  • No comments, no dates as a native type
  • Layout and formatting of the source document are not represented

Typical uses: Feeding document content into applications and scripts; APIs and configuration; Structured exports of tables and metadata.

What changes when you convert Excel (XLSX) to JSON

Tables and structured content are extracted into records. For spreadsheets this maps cells to rows and fields; for text documents it is best-effort and depends on how clearly the source is structured.
