Sheet Indexer uses AI to create a table of contents in your Google Sheet™. Save time by automatically indexing every tab with hyperlink navigation and descriptive summaries. 

$1.75 per month after a seven-day free trial.
 
Sheet Indexer connects to Google’s Gemini™ to generate summaries for each sheet. It also creates links to each sheet and summarizes the size, types of protection, and data types.

The generation of summaries may be rate-limited. This software is currently in a beta testing phase.
