Step 1 of 5

Pick a course

Every class you teach — active, not-started, or archived.

How it works

Four screens. Under a minute.

The whole flow is short on purpose — you came here to finish grading, not to learn an app.

Step 1
Pick your course
Sign in with Google. Every course you teach — active, just-created, or archived — appears in one list.
Step 2
Paste your sheet
Copy the Google Sheet URL from any browser tab. We read tabs and columns instantly.
Step 3
Map your columns
Pick grade + identifier (email, roll, or name). Auto-guessed from your header names.
Step 4
Preview & push
Every row verified against the class roster. Nothing touches Classroom until you confirm.

Two paths, one tool

When you'll need the webapp, when you'll need the extension.

Google's Classroom API has one ugly hole — assignments created in the Classroom UI don't accept grade writes. Here's where each surface fits.

Roll, name, grades

Every third-party tool hits this wall. Google's design choice.

No API, no OAuth — same flow as the webapp.

Webapp · the easy 95%

Use the webapp.Pick a course, paste your sheet, map columns, push. Drafts by default. Backups for 30 days. Sign in with Google and you're done.

Extension · for the API-blocked 5%

Add the Chrome extension.Google's API refuses grade writes on assignments their own UI created — every third-party tool hits this wall. The extension acts as your browser, not as an API client. No OAuth, no servers.

What makes it reliable

Built for messy real-world data.

The reason your last CSV export failed is the reason this exists.

Match by email, roll, or name

Personal-Gmail students whose email is hidden? Name-match fallback. Duplicate names → interactive resolver.

Real-world grade formats

"85", "85/100", "85%", "85 pts" — all parsed. Grades over max are flagged, not silently accepted.

Preview, then commit

See every match before anything is created in Classroom. If nothing matches, nothing is created. Period.

Unmatched row resolver

Dropdown from your roster for each unmatched row. Pick the right student or skip. Nothing is guessed.

Draft-first grading

Grades land as drafts. Review in the gradebook; publish when ready. Students never see a premature score.

Backup + one-click restore

Updating an existing assignment? Every previous grade snapshotted. Undo any push within 30 days.

For API-blocked assignments

Did you create the assignment in Classroom directly? There's a companion.

Google's API refuses grade writes on assignments the Classroom UI created. Our Chrome extension handles that exact case — runs inside your browser, no OAuth, no servers.

Chrome extension · v0.1.0

Sheet2Classroom for Chrome

Paste a grade range, see every match against your live roster, resolve unmatched rows with a dropdown — push.
Uses your existing Classroom session. No OAuth, no remote servers, no telemetry.
Grades update in place — no reloads, no refresh dance.

The split case, illustrated

Assignment created by Sheet2Classroom webapp: Push grades through the webapp. Uses Google's Classroom API. Backed up, restorable for 30 days.
Assignment created in the Classroom UI directly: Google's API refuses grade writes here — every third-party tool hits this wall. The extension handles it by acting as your browser, not as an API client. Same preview, same resolver, same one-click apply.

Questions

What teachers ask first.

Still have something? support@sheet2classroom.app.

+How do I export grades from Google Sheets to Google Classroom?

Paste your Google Sheet URL, map the identifier and grade columns, and hit Push. Sheet2Classroom creates (or updates) the Classroom assignment, writes grades as drafts so nothing is visible to students until you publish, and keeps a 30-day restorable backup in case you need to undo. No CSV file, no Apps Script, no copy-paste. See the step-by-step guide →

+Is this free?

Yes. Free to use. No accounts beyond Google, no paywall, no feature gates.

+What does Sheet2Classroom store?

We don't store grades or spreadsheet contents. Persisted data: an encrypted session cookie (for sign-in), last 100 push summaries for your history page (course name, timestamp, counts — no grade values), and temporary 30-day backups when you update an existing assignment. Operational logs keep email + course/assignment IDs for 30 days, then delete.

+What's the difference between a draft and a published grade?

A draft grade is saved on the Classroom submission but invisible to the student. We default to draft so you review before students see anything. Check the 'Publish' box to make grades visible immediately.

+Can I undo a push?

Yes — for updates to existing assignments. We take a full snapshot of previous grades before overwriting, and the result page + history page both surface a one-click Restore for 30 days. For brand-new assignments, if something went wrong, just delete the draft in Classroom.

+Do my students see the tool name on the assignment?

The assignment appears under the name "Gradebook" in Classroom — deliberately generic so the focus stays on the course, not the tool.

+What if the assignment was created in Classroom directly, not via the webapp?

Google's API refuses grade writes on assignments its own Classroom UI created — a limitation every third-party tool hits. We ship a Chrome extension that handles that case by running inside your own browser session (no OAuth, no servers). Paste grades, preview, apply — same flow as the webapp, but it works on the API-blocked assignments too. Install the extension →
