CTS Guard for Google Sheets™
Know your spreadsheet is clean before you send it
Customer lists, invoices, inventory, and platform exports usually live in one Sheets file that several people touch. CTS Guard checks that file where it already is.
Installs from the Google Workspace Marketplace™. Runs inside Google Sheets™, nothing to upload.
One sheet, several people, no formatting rules
Small teams move fast, and the spreadsheet takes the hit. By the time a file needs to go to a bookkeeper, a client, or a new tool, nobody is sure which rows are duplicates and which columns are safe.
- Customer records entered twice by two different people
- Emails with stray spaces or random capitalization
- Amount columns that mix text and numbers
- Exports pasted in with extra header and total rows
What CTS Guard checks
- Duplicate rows, exact and near matches
- Whitespace hiding inside cells
- Inconsistent email and name casing
- Numbers and dates stored as text
- Empty rows and columns
- Header rows that break an import
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.”
