CTS Guard for Google Sheets™
Review client spreadsheets before they enter your workflow
Clients send whatever their system exports. CTS Guard checks the tab in Google Sheets™ and shows the formatting problems that would slow down the month.
Installs from the Google Workspace Marketplace™. Runs inside Google Sheets™, nothing to upload.
Every client formats their data differently
One client exports from a POS, another types entries by hand, another sends a bank download with three header rows. The cleanup work happens before any real bookkeeping starts.
- Duplicate transaction rows from overlapping exports
- Amounts and dates stored as text
- Blank rows and totals sitting inside the data range
- Vendor names entered inconsistently across months
What CTS Guard checks
- Duplicate rows, exact and near matches
- Dates and numbers stored as text
- Whitespace inside cells
- Inconsistent vendor and description casing
- Empty rows and columns
- Header structure that blocks an import template
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.”
