CTS Guard for Google Sheets

Check rosters and class lists before they are shared

Class lists, contact sheets, and activity rosters are edited by many staff members. CTS Guard reviews the tab in Google Sheets and reports what looks off.

Install CTS Guard for Google Sheets

Installs from the Google Workspace Marketplace. Runs inside Google Sheets, nothing to upload.

Available on the Google Workspace Marketplace

Rosters change all year

Students move sections, contacts get updated, and exports get pasted into working tabs. The formatting drift shows up when a list needs to be shared or imported.

  • The same student listed twice after a section change
  • Contact emails with stray spaces
  • Dates entered as text
  • Exports pasted in with extra header rows

What CTS Guard checks

  • Duplicate rows, exact and near matches
  • Email and name formatting inconsistencies
  • Dates stored as text or mixed formats
  • Whitespace inside cells
  • Empty rows and columns
  • Header structure that blocks an import

How it works inside Google Sheets

  1. 1Open your sheet in Google Sheets and launch CTS Guard from the Extensions menu.
  2. 2Run a check. Guard scans the tab and shows what looks off, before anything changes.
  3. 3Apply the fixes you want. Your original values stay in the sheet until you approve a change.

Sheets schools teams already have

  • Class and section lists

    Duplicates created by mid year moves.

  • Contact sheets

    Inconsistent phone and email formatting.

  • Activity and club rosters

    Pasted exports with spacer rows.

  • Attendance trackers

    Dates stored as text so sorting fails.

Safe to send

Share a list internally without duplicate rows and formatting noise.

Import ready

Check the sheet before importing into another school system template.
