Export-IndexedDB-using-devtools-console

1.include-dexie-export-import.js

// On any web page that stores things in IndexedDB,
// open devtools and in the console, write the following:
script1 = document.createElement('script');
script1.src = 'https://unpkg.com/dexie@3.2.2';
document.body.appendChild(script1);
script2 = document.createElement('script');
script2.src = 'https://unpkg.com/dexie-export-import@1.0.3';
document.body.appendChild(script2);

2.set-var-theDBName.js

// In devtools "applications" tab navigate to IndexedDB and find
// the name of the databases to export. Then write:
theDBName = 'the name of the database you want to export';

3.export-db.js

// Export the database into a Blob:
theDB = new Dexie(theDBName);
let {verno, tables} = await theDB.open();
theDB.close();
theDB = new Dexie(theDBName);
theDB.version(verno).stores(tables.reduce((p,c) => {p[c.name] = c.schema.primKey.keyPath || ""; return p;}, {}));
theBlob = await theDB.export();

4.show-download-link.js

// The final step - show a download link to download the blob:
document.body.innerHTML = ` <a href="${URL.createObjectURL(theBlob)}">Right-click to download database export</a>`;

Try using dynamic imports. Just modify the db name at the start.

        const theDBName = 'YourDatabase';
        (async () => {
            await import('https://unpkg.com/dexie@3.2.2');
            await import('https://unpkg.com/dexie-export-import@1.0.3');
            await import('https://unpkg.com/downloadjs');
            let theDB = new Dexie(theDBName);
            let {verno, tables} = await theDB.open();
            theDB.close();
            theDB = new Dexie(theDBName);
            theDB.version(verno).stores(tables.reduce((p,c) => {p[c.name] = c.schema.primKey.keyPath || ""; return p;}, {}));
            theBlob = await theDB.export();
            download(theBlob, `${theDBName}.json`, "application/json")
        })();
