Understand the validator table before querying it
Start a review request and have Notis inspect the supporting table's columns and inferred types before you decide what to query.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Table Schema
This action is used to get the schema of a table in a google spreadsheet, call this action to get the schema of a table in a spreadsheet before you query the table. analyze table structure and infer column names, types, and constraints. uses statistical analysis of sample data to determine the most likely data type for each column. call this action after calling the list tables action to get the schema of a table in a spreadsheet.
Why this helps
Unclear headers and inconsistent table structure can make a targeted validator review harder to set up.
- See inferred table columns and types before querying.
- Surface structural assumptions for review.
- Make follow-up queries more informed.
Setup
Build it in a few focused steps.
- 1Connect Beaconchain and Google Sheets once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for validator schema checks.
- 3Tell Notis to analyze the requested Beaconchain validator and inspect the supporting table schema.
- 4Pick a webhook trigger, then choose where run reports should go.
- 5Test with one real table and review the inferred column names and types.

Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Aggregate Column Data
Searches for rows where a specific column matches a value and performs mathematical operations on data from another column.
Append Dimension
Tool to append new rows or columns to a sheet, increasing its size. use when you need to add empty rows or columns to an existing sheet.
Batch get spreadsheet
Retrieves data from specified cell ranges in a google spreadsheet; ensure the spreadsheet has at least one worksheet and any explicitly referenced sheet names in ranges exist.
Batch update spreadsheet
Updates a specified range in a google sheet with given values, or appends them as new rows if `first cell location` is omitted; ensure the target sheet exists and the spreadsheet contains at least one worksheet.
Batch Update Values by Data Filter
Tool to update values in ranges matching data filters. use when you need to update specific data in a google sheet based on criteria rather than fixed cell ranges.
Clear Basic Filter
Tool to clear the basic filter from a sheet. use when you need to remove an existing basic filter from a specific sheet within a google spreadsheet.
Clear spreadsheet values
Clears cell content (preserving formatting and notes) from a specified a1 notation range in a google spreadsheet; the range must correspond to an existing sheet and cells.
