Can I get one Doc per note?

Not from one file. Use the Markdown export and Drive's Markdown support, or the HTML archive to keep everything browsable in one page.

Export Google Keep to Google Docs

Keep's “Copy to Google Docs” works one note at a time. To get everything into one document, convert your Takeout zip to a .docx here and upload it to Drive, which opens it as a Google Doc with a page per note.

Drop your Google Takeout zip here

or the unzipped Takeout/Keep folder, or its .json files. Nothing is uploaded — the conversion runs in this tab.

Import into Google Docs

You get: One .docx file.

Download the .docx.
In Google Drive: New → File upload → pick the .docx.
Open it; Drive converts it to a Google Doc (or right-click → Open with → Google Docs).

What carries over

Title, text and formatting
Checklists with ☐ / ☑ marks
Images
Labels and dates under each title

Good to know

Very large exports (thousands of photos) make a big document; filter by label to split it.

Getting the export from Google

Open Google Takeout, deselect everything, select Keep, and create a zip export. Google emails a download link; the zip contains a Takeout/Keep folder. Drop that zip above. Full walkthrough: how to export Google Keep.
