Dynamic column creation from webhook data
Webhook delivers a new data type? Notis automatically creates a column for it in your sheet, so you're never catching up with missing structure.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create spreadsheet column
Creates a new column in a google spreadsheet, requiring a valid `spreadsheet id` and an existing `sheet id`; an out-of-bounds `insert index` may append/prepend the column.
Why this helps
External webhooks deliver variable data, and you have to manually add new columns every time a new field appears, creating friction.
- Adapts to changing data structures without manual intervention
- Reduces setup friction for integrating new external tools
- Keeps your sheet structure aligned with incoming data
- Eliminates the cognitive load of manual column creation
Setup
Build it in a few focused steps.
- 1Connect Google Sheets to Notis.
- 2Create an automation: 'When I send a webhook with data, add any new columns that don't already exist in my sheet.'
- 3Get your unique webhook URL from Notis and set it up in your external tool or app.
- 4Configure the external tool to send data with column headers in the JSON payload.
- 5Test by sending a sample webhook and verifying that missing columns are created automatically.
Questions about this workflow
What if I don't want all webhook fields as columns?
Tell Notis which fields to ignore. For example, 'Only create columns for event, status, and user_id; skip internal metadata.'
Can I set column order?
Yes. Specify a column order in your automation prompt, and Notis will create them in that sequence.

Supported Triggers and Actions
Notis builds workflows that link Google Drive to Google Sheets. A trigger fires from one place; an action lands in another.
Google Drive triggers
Google Sheets actions
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Add Sheet to Spreadsheet
Adds a new sheet (worksheet) to a spreadsheet. use this tool to create a new tab within an existing google sheet, optionally specifying its title, index, size, and other properties.
File Created
Triggers when a new file is created in Google Drive.
Aggregate Column Data
Searches for rows where a specific column matches a value and performs mathematical operations on data from another column.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
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.
File Shared (Permissions Added)
Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
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.
File Updated
Triggers when a file's metadata or content changes in Google Drive.
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.
Google Drive Changes
Triggers when changes are detected in a Google Drive.
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.
New File Matching Query
Triggers when a new Google Drive file matches a provided query. This is the legacy query-centric trigger: it preserves Drive API query config such as ``corpora`` / ``driveId`` aliases and emits the historical ``file_matching_query`` event type. ``FileCreatedTrigger`` covers the broader "new file" case and emits ``file_created``.
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.
