Excel Plugin

The Excel plugin brings Langdock into Microsoft Excel, so your spreadsheets and AI assistance stay side by side. Use it to understand workbooks faster, create formulas, clean up data, and turn spreadsheet findings into clear summaries without switching tools. You can ask questions while looking at your workbook, iterate on outputs directly in Excel, and keep your analysis in the place where the work is happening.

​

Working with Langdock in Excel

The Excel plugin is useful whenever the work starts in a spreadsheet. Instead of copying data into a separate chat, you can keep Excel open and use Langdock alongside it.

​

Common use cases

• Build tables and plans: Ask Langdock to create budget plans, project trackers, comparison tables, or reporting templates directly in your workbook.
• Create calculations: Describe the calculation you need and let Langdock add formulas, totals, percentages, or growth rates.
• Clean and structure data: Standardize names, dates, categories, currencies, or messy rows before you analyze them.
• Analyze spreadsheet results: Ask Langdock to find trends, outliers, changes, and key takeaways in your data.
• Research and enrichment: Use Langdock to research companies, markets, or topics and add useful context to your spreadsheet.
• Prepare summaries: Turn spreadsheet findings into updates for reports, emails, presentations, or team meetings.

​

Example: Build a quarterly budget plan

Say you need to create a quarterly budget plan with department-level cost breakdowns. Open the Langdock Add-in next to your workbook and describe what you want to build. Ask Langdock for the spreadsheet you need: Build a quarterly budget plan with department-level cost breakdowns Langdock creates the table in your workbook and keeps the conversation open next to it. From there, you can ask follow-up questions, analyze the table, perform calculations, or use connected integrations without leaving Excel.

​

Next steps

After Langdock creates the first output, you can keep working from the same panel:

• Ask follow-up questions about the sheet
• Add calculations, totals, or comparisons
• Enrich the spreadsheet with results from a Web Search
• Draft an email by using Actions in Chat and selecting your email provider from your connected integrations

Save to Library

You can save files from the Excel plugin directly to your Langdock Library, making them accessible to your Workspace and team. Save to the Library root or choose a specific Folder to organize files for everyone with access.
