Prerequisites

Before installing, confirm the following:

  • Supported Excel version: Microsoft Excel for Microsoft 365 or Excel ⁄2021 on Windows or macOS (check Helium’s system requirements for exact versions).
  • Operating system: Windows ⁄11 or macOS 10.15+ (verify current compatibility).
  • Permissions: Administrative privileges may be required to install system-wide add-ins on some machines. If you can’t install, ask your IT admin.
  • Internet connection: Required for download, activation, updates, and cloud features.
  • Microsoft account / Office activation: Excel should be activated and logged in with the account you use for Office.
  • Excel settings: Enable external content and add-ins in Excel’s Trust Center if your environment blocks add-ins by default.

Step 1 — Downloading Helium for Excel Community Edition

  1. Visit Helium’s official download page for the Excel add-in.
  2. Choose the Community Edition download (look for “Community Edition” or “Free” label).
  3. Select the correct installer for your OS (Windows .exe/.msi or macOS .pkg).
  4. Save the installer to a known folder.

Tip: If your organization blocks direct downloads, ask IT to provide the installer or an approved distribution channel.

Step 2 — Installing on Windows

  1. Close Excel and any Office applications.
  2. Double-click the downloaded .exe or .msi file to start the installer.
  3. If prompted by User Account Control (UAC), choose Yes to allow installation.
  4. Follow the installer steps:
    • Accept the license agreement.
    • Choose installation scope (per-user or system-wide). Per-user is sufficient for most personal setups and avoids admin prompts.
    • Select installation folder or accept default.
  5. Click Install and wait for the process to complete.
  6. When finished, click Finish and open Excel.

Note: If the installer offers optional components (e.g., connectors, templates), select the ones you need — you can usually add them later via Helium’s settings.

Step 3 — Installing on macOS

  1. Close Excel and other Office apps.
  2. Double-click the downloaded .pkg file.
  3. Follow the installer prompts and authenticate with your macOS password if requested.
  4. Install to the default location unless you have a specific reason to change it.
  5. When installation completes, open Excel.

Step 4 — Enabling the Add-in in Excel

If Helium does not appear automatically after installation, enable it manually:

Windows (Excel):

  1. File > Options > Add-ins.
  2. At the bottom, choose Manage: COM Add-ins (or Excel Add-ins) and click Go.
  3. Look for “Helium for Excel” in the list and check the box.
  4. Click OK and restart Excel if necessary.

macOS (Excel):

  1. Tools > Excel Add-ins (or Insert > My Add-ins depending on Excel version).
  2. Locate Helium and enable it.
  3. Restart Excel if it does not load immediately.

Step 5 — Initial Setup and Sign-in

  1. With Excel open, locate the Helium tab on the ribbon (often alongside Data, Insert, and other add-ins).
  2. Click the Helium tab, then click Sign In or Activate.
  3. Sign in with the account required by Helium (this may be a Helium account, Microsoft account, or organizational SSO).
  4. Grant any requested permissions (data access, file access, identity). Read permissions carefully — Helium needs certain permissions to integrate with Excel and cloud features.
  5. If you use an organizational SSO, you may be redirected to your company’s authentication portal.

If you prefer to use offline or limited features, look for a “Use offline mode” or “Limited/Local mode” option during sign-in or in Settings.

Step 6 — Configure Core Settings

Open Helium’s Settings (often a gear icon or Settings menu in the Helium ribbon) and adjust key options:

  • Account/Profile: Verify your account and subscription status (Community Edition should show as active and free).
  • Default workspace: Choose a workspace or folder where templates and project files are stored.
  • Update preferences: Enable automatic updates or set manual check frequency. Community Edition often allows automatic patching.
  • Privacy & telemetry: Toggle telemetry/usage reporting according to your preference.
  • Data connectors: Enable and configure connectors (Google Sheets, SQL databases, cloud storage). Provide credentials or connection strings as needed.
  • Add-in behavior: Configure whether Helium opens on Excel startup, shows tips, or displays notifications.
  • Language & region: Set locale for date/number formats if relevant.

Recommended settings for most users:

  • Enable automatic updates.
  • Allow only necessary connectors; add more when needed.
  • Keep telemetry off if you want maximum privacy.

Step 7 — Install or Import Templates and Sample Projects

Helium often includes sample templates and pre-built flows to help you get started.

  1. In the Helium ribbon, look for Templates, Samples, or Gallery.
  2. Browse available templates for tasks such as data cleansing, forecasting, or dashboard creation.
  3. Click Import or Install for templates you want.
  4. Open a sample workbook to see Helium’s features in action.

This helps you learn typical workflows and accelerates building your own solutions.

Step 8 — Connect to Data Sources

To use Helium effectively, connect to your data:

  1. Open Helium’s Data Connectors panel.
  2. Choose a connector: Excel tables, CSV, Google Sheets, SQL Server, MySQL, PostgreSQL, BigQuery, cloud storage (S3, Azure Blob), APIs, etc.
  3. Enter credentials or connection strings and test the connection.
  4. Save secure credentials in Helium’s vault or use OS keychain/SSO if available.
  5. Import or link the dataset into your workbook.

Tip: For sensitive databases, use read-only credentials and limit access by IP or VPN where possible.

Step 9 — Configure AI & Processing Options

Helium’s AI features may require specific configurations:

  • Model selection: Choose available models or local processing options (Community Edition might limit premium models).
  • Token and request limits: Set usage caps to avoid excessive API calls or costs.
  • Prompt templates: Create and save prompt templates for repeated tasks (summaries, transformations, formulas).
  • Caching: Enable result caching where available to speed repetitive queries.

Be mindful of data privacy: avoid sending highly sensitive data to external models unless you understand the data handling policy.

Step 10 — Verify Installation and Run a Test Workflow

  1. Open a new or sample workbook and create a small dataset (3–10 rows).
  2. Use Helium’s quick actions: clean a column, generate a summary, or create a chart via the add-in.
  3. Confirm the result appears as expected and that no errors occur.
  4. Check Helium’s logs or activity panel for successful operations.

If the test fails, consult the troubleshooting section below.

Troubleshooting

  • Add-in not visible:

    • Ensure Excel is fully closed during installation.
    • Enable the add-in via File > Options > Add-ins.
    • Check Excel’s Disabled Items and re-enable Helium if listed.

  • Installation fails or shows permissions error:

    • Re-run the installer as Administrator (Windows) or use an admin account (macOS).
    • If enterprise policies block installers, ask IT to deploy via MS Intune, JAMF, or your software distribution tool.

  • Sign-in/activation issues:

    • Confirm correct account type (Helium account vs Microsoft/SSO).
    • Clear saved credentials in Windows Credential Manager or macOS Keychain and retry.
    • Check organization’s SSO settings or conditional access policies.

  • Connectors fail to authenticate:

    • Verify credentials and network access (VPN, firewall).
    • Test the connection outside Excel (e.g., database client) to isolate the problem.
    • Ensure required client drivers (ODBC, database clients) are installed.

  • Slow performance:

    • Disable unneeded connectors and background sync.
    • Increase Excel memory limits by closing other large workbooks or apps.
    • Use smaller preview datasets when designing workflows.

  • Unexpected errors or crashes:

    • Update Helium and Excel to the latest versions.
    • Check Helium’s logs (in Settings) and share with support if needed.
    • Reinstall Helium after uninstalling and rebooting.

Best Practices

  • Keep Helium and Excel updated to receive bug fixes and security patches.
  • Use version control for important workbooks (save versions or use cloud backups).
  • Store credentials in secure vaults or use SSO where possible.
  • Use read-only database credentials for analysis-only workflows.
  • Limit data sent to cloud AI models; anonymize sensitive fields before processing.
  • Start with sample templates to learn patterns, then build tailored workflows.
  • Document your Helium workflows and settings for team onboarding.

Uninstalling Helium

Windows:

  1. Settings > Apps > Find Helium for Excel > Uninstall.
  2. Alternatively, use Control Panel > Programs and Features.
  3. Restart Excel and verify the Helium tab is gone.

macOS:

  1. Use the uninstaller if provided, or remove the Helium app from Applications.
  2. Remove leftover add-in files from ~/Library/Application Support or ~/Library/Containers if necessary.
  3. Restart Excel.

Also clear saved credentials from system keychain or credential manager if you plan to remove access completely.

Conclusion

Installing and configuring Helium for Excel Community Edition involves downloading the correct installer, enabling the add-in in Excel, signing in, and adjusting core settings—especially data connectors and AI options. Use sample templates and test workflows to confirm everything works, and follow security best practices for credentials and sensitive data. If you run into problems, the troubleshooting steps above cover common issues and fixes.
