CTS Guard for Google Sheets™
Stop shipping messy spreadsheets to investors and customers
Lead lists, metrics tabs, and pipeline sheets get built fast and shared faster. CTS Guard checks the tab in Google Sheets™ before it goes out.
Installs from the Google Workspace Marketplace™. Runs inside Google Sheets™, nothing to upload.
The spreadsheet is the system, until it is not
Early on, one Sheets file holds leads, revenue, and the pipeline. It works right up to the moment someone outside the team reads it, or a tool tries to import it.
- Duplicate leads from several import sources
- Emails with inconsistent casing and stray spaces
- Metrics columns mixing text and numbers
- Pasted exports with extra header and total rows
What CTS Guard checks
- Duplicate rows, exact and near matches
- Whitespace and casing inconsistencies
- Numbers and dates stored as text
- Empty rows and columns
- Header structure that breaks a CRM import
- Column naming that will confuse a downstream tool
How it works inside Google Sheets™
- 1Open your sheet in Google Sheets™ and launch CTS Guard from the Extensions menu.
- 2Run a check. Guard scans the tab and shows what looks off, before anything changes.
- 3Apply the fixes you want. Your original values stay in the sheet until you approve a change.

The FAQ
CTS Guard for other teams
“We've found this tool to be a great fit for the kind of spreadsheet work we do at Lombard Toyota. It helps turn large, messy data exports into something much easier to read and work with, without requiring a lot of manual cleanup.
What we especially like is that it seems to understand the structure of dealership data instead of treating every column the same. That saves time and makes the finished spreadsheets much more useful for our day-to-day work.
Definitely a helpful tool for an automotive dealership working with a lot of data.”
