Alt Text for Data Visualizations

By Posit

Generate accessible descriptions for charts and images in your documents.

Simple Excel

• Reads and writes Excel (.xlsx) and CSV files
• Filters rows, selects columns, and sorts data by any field
• Performs calculations like sums, averages, and group totals
• Adds new columns with formulas combining existing data
• Exports results to new spreadsheets or specific sheets

Alt Text for Data Visualizations

• Generates alt text for charts in R packages and Quarto documents following accessibility guidelines
• Uses your actual chart code to identify exact variables, data patterns, and visual elements
• Structures descriptions with chart type, data details, and key insights in plain language
• Ensures alt text complements rather than duplicates your existing captions
• Adapts description length and detail based on chart complexity

Reach for Simple Excel when…

• You need to pull specific data from a large spreadsheet without opening Excel
• You're combining data from multiple CSV files into one report
