Nexalys

Nexalys is an AI assistant built into Excel that helps you understand, analyze, and modify your workbooks more efficiently, with a clearer, more guided, and more controlled experience.

Account creation & support (first use)

A Nexalys account is required to use the assistant in Excel.

• Create an account: on first launch, click Create an account directly in the Nexalys task pane.
• Need help / contact: visit the support page at https://nexalys.compagnyservices.com/support/.

Pricing, subscriptions, and credits

The add-in is free to install. Nexalys works with a free plan, paid subscriptions, and credit packs depending on your usage.

• Offer details, credits, and applicable conditions are available in the Store / Billing section inside the add-in, as well as on the Nexalys pricing page.
• You can start with the free experience and then move to a paid plan or purchase additional credits depending on your needs.

A practical AI assistant for Excel

Nexalys helps you move faster inside Excel without leaving your file. For example, you can ask it to:

• explain a formula or a calculation;
• summarize a worksheet or a table;
• find specific information in a workbook;
• prepare certain changes in Excel;
• help clean or make data more usable.

Preview, control, and understanding

Nexalys is designed to remain understandable inside Excel.

• When a modification is proposed, a preview may be shown before validation when Preview mode is used and when relevant.
• You can ask Nexalys to explain what it understood, what it proposes, and the logic it followed.
• The goal is not to replace your judgment, but to help you move faster with more visibility.

A learning assistant to improve your Excel skills

Nexalys is not only about getting a result. It can also help you better understand Excel along the way.

• Explain formulas, calculations, and worksheet logic in clear language.
• Clarify useful steps to reach a result in a workbook.
• Help users progress with a more guided, more readable, and more structured approach.

Trust, caution, and privacy

Nexalys is designed with a focus on clarity, minimization, and caution.

• The assistant processes the elements useful to your request, to the extent necessary for the service to function.
• The product is designed to limit data reading and processing to what is strictly necessary.
• Additional information about data handling is available in the Nexalys privacy policy.

Nexalys is in beta

Nexalys is an evolving product. Like any AI assistant, it may make mistakes, misunderstand a request, or suggest an imperfect action.

• We recommend reviewing results before validation, especially on important, sensitive, or third-party files.
• Nexalys should be used as an assistant, not as an automatic validation system.

Real-world examples

• Data cleaning: fix dates, harmonize values, detect inconsistencies, or make a table more usable.
• Workbook understanding: explain a formula, summarize a worksheet, or clarify the logic of an existing file.
• Help with execution: prepare certain modifications or help structure a result directly in Excel.
• Learning support: help users better understand what they are doing in Excel.

Who is it for?

• Beginners who want cleaner results without mastering every Excel function.
• Intermediate users who want to work faster and reduce mistakes.
• Advanced users who want to save time on recurring Excel tasks while keeping more visibility.

Summary

Nexalys helps you work better in Excel with more clarity, more control, and more understanding. It saves time on repetitive work while keeping you actively involved in reviewing the results.
