CSV Import+Export

CSV Import+Export is an Excel add-in which adds the ability to import and export CSV files.

Dev build

Requires Node.

1. Open a blank worksheet on Excel Online. Go to Insert | Office Add-ins. On the top right hand corner under Manage My Add-ins, click Upload my Add-In. Upload manifests/dev.manifest.xml.

2. Run npx office-addin-dev-certs install to get https certificates that Excel accepts.

3. Run the following commands to start webpack-dev-server.

npm i
npm run devServer

4. Go back to Excel and open CSV Import+Export.

• Having both the published version and your dev version of CSV Import+Export installed can get confusing. I recommend removing the published version so you know which one you are working on.
