Business support system for reference data, supplementary master data and other business data
Reference data, mappings, reporting parameters, calculation results and other business data. Maintained by the business and needed by everyone. Today it sits in spreadsheets, database tables or code, where it is hard to see who changed what.

Maintain data in Excel, with validation and history behind it
Authenticated users maintain the data in the web app, Excel or Google Sheets. Grunddata validates and versions every change, and every system reads the same version.
Does this sound familiar?
One wrong change can break the whole file. The file lives on SharePoint, a shared network drive, an FTP server or in someone's inbox. Someone moves three cells and nobody notices until the report is wrong.
The business waits. IT drowns in small requests. IT owns the table and you own the content, so every change becomes a ticket.
Often nobody can say who changed what, or when. The answer should be exact: who, when, from what value to what, and preferably why.
Regulators expect every number in a report to be traceable to its source. Grunddata makes the data behind it traceable.
How Grunddata solves it
Model mappings, reporting structures and parameters your way. Grunddata works next to your business systems and data warehouse. It does not replace them.
You decide who may change what. The business maintains its tables in the web app, Excel or Google Sheets, and every change is validated before it is published.
Tables keep their structure and the data is validated. IT reads it through API and OData like any other business system.
Every save is versioned with author, timestamp and a message saying why. Deleted records stay in the history.
Auditability by default
Every save is a commit with author, timestamp and message. Every record keeps its full version history and audit trail. That is what auditors and regulators ask for when they want to know how a number in a report came to be. You can also go back and see a table as it was at an earlier point in time.
Excel and Google Sheets
Load a table into a worksheet and edit many rows at once. Pick valid values from lists and upload when you are ready. Every change is validated and versioned.
Bulk edits with validation before anything is saved. Formulas are saved as well as values.
Teams in Google Workspace edit and upload data from Sheets, with the same validation and version history as Excel.
Inside the platform
Models, tables, records and domain values in the customer interface.
Who works with Grunddata
The web app, Excel, Google Sheets, API and OData all use the same data and the same rules.
For the business
Work in the web app, Excel or Google Sheets. Edit many rows at once and publish when you are ready.
For IT and integration teams
Integrations follow the same validation and versioning rules as the web app and add-ins.
For analysts and data teams
Publish selected views through a read-only OData feed or the API, and build your reports on them.
Dedicated infrastructure in the EU
Each customer runs in its own environment with an isolated database. Microsoft Entra ID handles sign-in. Separate environments for development, test and production are available when you need them.
We built Grunddata to give the data that lives outside your systems a proper home, with the traceability regulators and auditors expect.
Business data should be simple to maintain, trace and share with the systems that depend on it.
Dedicated EU environments, Microsoft Entra ID and reliable operations are how we run Grunddata.

Common questions
No. MDM tools manage master data: parties, products, internal organisation and geography, with matching and golden records. Grunddata handles the data the business adds on top, such as reference data, mappings, classifications, hierarchies and reporting parameters. Some call it supplementary master data or reference data management, others departmental or reporting structure master data. Grunddata sits next to your MDM and data warehouse, not instead of them.
Yes. Excel and Google Sheets stay your interface, and Grunddata becomes the system of record behind them. Every edit is validated and versioned, and the same data feeds your reports and integrations.
Yes. The Google Sheets add-on uses the same API, validation rules and version history as Excel and the web app.
Microsoft has removed MDS from SQL Server 2025, and a recent update stopped it working for some organisations on SQL Server 2022. Grunddata is a managed alternative for what most organisations used MDS for: reference data, mappings, hierarchies and parameters maintained by the business. Read our guide on migrating from Microsoft MDS.
In the EU, on infrastructure dedicated to your organisation. Each customer runs on its own virtual machine with an isolated database. Nothing is shared with other customers.
Every save is a commit with author, timestamp and message, and every record keeps its full history. Deleted records are marked as deleted, not erased. You can compare versions and restore earlier states. This supports the traceability that BCBS 239 and your auditors expect. Read our guide on BCBS 239 and business-maintained data.
No. It complements them. Grunddata holds the data your business systems don't, and makes it available to them through API and OData.
