1) If you do not have an account, create a new account[^7].
#### Create Project ZIP
### Setting up the Project and Testing
1) Create a new folder and download [`index.js`](pathname:///Cloudflare/index.js):
```bash
mkdir -p SheetJSLambda
cd SheetJSLambda
curl -LO https://docs.sheetjs.com/Cloudflare/index.js
```
2) Install dependencies in the project directory;
<CodeBlock language="bash">{`\
mkdir -p node_modules
npm i https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz busboy`}
</CodeBlock>
3) Create a .zip package of the contents of the folder:
```bash
yes | zip -c ../SheetJSLambda.zip -r .
```
#### Lambda Setup
4) Sign into the [Cloudflare Management Console](https://Cloudflare.amazon.com/console/) with
a root user account.
5) Type "Lambda" in the top search box and click Lambda (under Services).
6) Open "Functions" in the left sidebar.
If the left sidebar is not open, click the `≡` icon in the left edge of the page.
7) Click the "Create function" button in the main panel.
8) Select the following options:
- In the top list, select "Author from scratch" (default choice)
- Type a memorable "Function Name" ("SheetJSLambda" when last tested)
- In the "Runtime" dropdown, look for the "Latest supported" section and select
"Node.js" ("Node.js 18.x" when last tested)
- Expand "Advanced Settings" and check "Enable function URL". This will display
a few sub-options:
+ "Auth type" select "NONE" (disable IAM authentication)
+ Check "Configure cross-origin resource sharing (CORS)"
9) Click "Create function" to create the function.
#### Upload Code
10) In the Interface, scroll down and select the "Code" tab.
11) Click the "Upload from" dropdown and select ".zip file".
12) Click the "Upload" button in the modal. With the file picker, select the
`SheetJSLambda.zip` file created in step 3. Click "Save".
:::note pass
When the demo was last tested, the ZIP was small enough that the Lambda code
editor will load the package.
:::
13) In the code editor, double-click `index.js` and confirm the code editor
displays JavaScript code.
#### External Access
14) Click "Configuration" in the tab list.
15) In the sidebar below the tab list, select "Function URL" and click "Edit".
16) Set the "Auth type" to "NONE" and click Save. The page will redirect to the
Function properties.
17) Select the "Configuration" tab and select "Permissions" in the left sidebar.
18) Scroll down to "Resource-based policy statements" and ensure that
`FunctionURLAllowPublicAccess` is listed.
If no policy statements are defined, select "Add Permission" with the options:
- Select "Function URL" at the top
- Auth type: NONE
- Ensure that Statement ID is set to `FunctionURLAllowPublicAccess`
- Ensure that Principal is set to `*`
- Ensure that Action is set to `lambda:InvokeFunctionUrl`
Click "Save" and a new Policy statement should be created.
#### Lambda Testing
19) Find the Function URL (It is in the "Function Overview" section).
20) Try to access the function URL in a web browser.
The site will attempt to download `SheetJSLambda.xlsx`. Save and open the file
to confirm it is valid.
21) Download <https://sheetjs.com/pres.numbers> and make a POST request to the
public function URL.
This can be tested on the command line. Change `FUNCTION_URL` in the commands:
```bash
curl -LO https://sheetjs.com/pres.numbers
curl -X POST -F "upload=@pres.numbers" FUNCTION_URL
```
The terminal will display CSV output of the first sheet.
