To follow in the footsteps of the masters and create spreadsheets that are both functional and professional, experts like those at the University of Iowa suggest these core principles: Keep it Rectangular: You do not need a paid course or

In the vast ecosystem of data management, few names are as synonymous with a specific tool as is with spreadsheets . While most users interact with Excel, Google Sheets, or Airtable at a surface level—inputting data, running basic sums, and creating simple charts—a new class of power user has emerged.
