Keep the sheet from becoming the reason the work stalls.
The goal is the send, upload, import, or handoff. Clean That Sheet Guard™ gives the Google Sheet one more check before the work moves forward.
Catch blanks, duplicates, formatting issues, spreadsheet errors, and missing headers without making cell-by-cell inspection your whole job.
Works directly with Google Sheets™.
A second set of eyes so the work can go where it needs to go.
Spreadsheets often look fine until they are imported into another system, shared with a client, handed to a teammate, or used for an operational workflow.
CTS Guard gives you a quick preflight check so you can catch common issues before they become downstream problems.
Before you share
Check a spreadsheet before sending it to a client, coworker, or partner.
Before you upload
Catch issues that may cause problems when uploading spreadsheet data into another platform.
Before you import
Review data quality before importing CSV or spreadsheet records into another system.
Check your sheet in a few clicks.
- 1
Open your spreadsheet
Use CTS Guard directly inside Google Sheets™.
- 2
Run a check
Choose the type of review you need and let Guard scan the sheet for common issues.
- 3
Review before you move forward
See what was flagged, make corrections, and continue with more confidence.
“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.”
