The SQLSeal plugin enables Obsidian users to transform CSV files in their vault into SQL databases for advanced querying. By creating `sqlseal` code blocks, users can define tables based on CSV files and execute SQL statements like `SELECT`, providing powerful data manipulation and analysis capabilities directly within Obsidian. Multiple tables can be defined in a single snippet, and tables remain local to the note for efficient organization. This plugin is ideal for managing and querying structured data within a vault, seamlessly integrating database functionality into the note-taking environment.

The SQLSeal Charts plugin extends SQLSeal by enabling data visualization through a variety of chart types. It integrates with ECharts, allowing users to transform SQL query results into line, bar, pie, scatter, and heatmap charts within Obsidian. By leveraging SQLSeal’s querying capabilities, users can structure and manipulate data before displaying it graphically. The plugin provides built-in functions to process and refine datasets, making it suitable for users who want to analyze structured information directly in their notes.
