Usage

What languages are supported?

FormulaBoost can parse formulas in any language. For example, some of our non-English language customers include Polish, French and Spanish.

Can it be used offline?

Yes. After the initial install, FormulaBoost can be used for an extended period of time (multiple weeks) without internet access.

Will it slowdown Excel?

No. FormulaBoost was made for professional users of Excel and is designed to be as unobtrusive and performant as possible.

The app's code only runs when you use one of its features. If you don't use a feature — you won't notice it's there. Additionally, Excel's start-up time is miminally affected (less than 200 milliseconds).

Is it actively maintained and improved?

Yes. FormulaBoost launched in 2019 and 2024/2025 saw some of the largest changes to date. Much more is planned for the future.

Is technical support offered?

Yes. Technical support is included with all paid and trial versions.

What kind of formulas can be parsed?

FormulaBoost is designed to parse all valid Excel formulas. This includes new Excel features such as the @ and # symbols for dynamic array support.

What languages are supported?

FormulaBoost can parse formulas in any language. For example, some of our non-English language customers include Polish, French and Spanish.

Why is FormulaBoost being flagged as containing viruses by my anti-virus software?

Please read more about anti-virus false positives on this page.

Does FormulaBoost work with Excel Online or Excel for Mac?

No. FormulaBoost runs on the Windows desktop environment exclusively.

What kind of add-in is this?

This is a COM add-in not a VBA add-in. This means code is written in more powerful and performant languages compared to VBA.

Can I install FormulaBoost at work?

Yes you can since the installer file is set to not require administrator rights.

Installation

Are administrator rights required to run the installer?

No. Unless your IT policy has extra restrictions, the installer can be run on your workplace computer without intervention.

Does the trial version include all features of the add-in?

Yes, the free trial is identical to the paid version. There are no restrictions on the free trial other than the length of its use.

What are the system requirements?

You can find the full details here, but in short, FormulaBoost runs on virtually any modern Windows computer with Excel — no additional software required.

Why am I downloading an installer (.msi) and not an Excel add-in file (.xlam)?

The installer determines which version of Excel you have and its bitness (32 or 64 bit), and allows for easier upgrades. FormulaBoost is not a VBA add-in.

What happens when the free trial ends?

A license can be purchased to continue using the add-in or it can uninstalled via the Add/Remove Windows feature or by disabling the add-in from within Excel. There are no nag screens or pop-ups when the trial expires.

Licensing

Does my license auto-renew?

No, there are no recurring charges. If you have a non-perpetual license, then at expiry a new license must be purchased to continue using the add-in.

What is a perpetual license?

A FormulaBoost perpetual license allows the license holder to use FormulaBoost indefinitely, though it places restrictions on the length of time after purchase that a license holder can upgrade to newer versions.

What is a non-perpetual (termed) license?

A FormulaBoost non-perpetual license allows the license holder to use FormulaBoost for a period of time as determined upon purchase, after which date all features of the add-in become disabled.

Can a license be transferred to a new computer?

Yes, there are no restrictions on the number of transfers of a purchased license, though a single license can only be active on one computer at any given time.

Can I purchase multiple keys for my company?

You can purchase up to 50 keys from the pricing page. For larger orders, please contact us.

Is my payment secure?

What happens after I make a purchase?

After purchase, you are redirected back to our website and your license key will be displayed to you. Your license key is also emailed to you. Your key can be activated from within Excel.
