No. The Import Export PowerTool does not overwrite or replace any of your existing Microsoft Dynamics 365 Business Central permission sets. This is a completely free app from Insight Works for Business Central. It adds two permission sets of its own, a manager set and a user set, and otherwise relies entirely on the access rights you have already configured for each user. Your current security model stays intact after installation.
What the tool adds and what it leaves alone
When you install the tool, it introduces two new permission sets that control how people interact with the tool itself. The manager set allows editing the setup page, including the options for update, delete, disabling the change log, and access to protected tables. The user set allows running the tool but not changing those settings. Beyond adding these two sets, the tool makes no changes to the permission sets already assigned to your users. Nothing in your existing access configuration is altered, removed, or merged.
It enforces, rather than bypasses, existing access
A common worry is that a tool with broad data capabilities might let users act outside their normal rights. The Import Export PowerTool works the opposite way. Even when you grant someone the ability to import, update, or delete through the tool, the operation still checks that user’s underlying Business Central permissions on the affected table. If a user lacks permission to modify a given table in Business Central, they cannot modify it through the tool either. The tool layers its own controls on top of native security; it does not weaken or rewrite it.
The one area where the tool extends reach
There is a single, deliberate exception worth understanding. Business Central marks certain ledger tables, such as item ledger entries, as protected and does not normally allow direct editing of them through the standard interface. When an administrator enables access to protected tables in the tool’s setup, an authorized user can reach those tables. This is an added capability granted through the tool’s own setting, controlled by the manager permission set, and not a change to any existing permission set. If protected table access is left disabled, those tables remain off limits.
How to assign the two permission sets
Assign the manager permission set to administrators who should configure the tool and reach protected tables. Assign the user permission set to operators who should only run imports, exports, updates, or deletes within their normal Business Central rights. Because these sets sit alongside your existing assignments, you can adjust them at any time without disturbing the rest of your security design.

Import Export PowerTool is the Insight Works app for fast import, export, update, and delete operations in Business Central. Its manager and user permission sets govern access to the tool and its setup options while leaving all other permission sets untouched.
Installing the tool is safe from a security standpoint because it does not overwrite your permission configuration. It adds two scoped permission sets, honors every user’s existing Business Central access, and only extends reach to protected tables when an administrator explicitly enables that option.
