Version 10.1, August 17, 2022

Breaking Changes

The add-in does not activate saving changes for views, procedures, and SQL code objects based on joining multiple tables. To save changes for such objects, you must manually set the target table in the xls.objects table.

New Features

The add-in supports SaveToDB Framework settings for OData, ODataDB, and DBGate objects, similar to database settings. It supports tables and views in xls.objects, xls.handlers, xls.translations, xls.formats, and xls.workbooks. For OData services, just publish such objects as EntitySets. For ODataDB and DBGate services, the add-in reads such settings from metadata automatically.
The add-in allows selecting fields with OData and DBGate queries by adding the $select variable to the query URL.
The add-in supports saving changes to EntitySets using Change handlers similar to database tables.

Resolved a problem where inserting and updating tables with table totals enabled did not work with .NET providers.

Version 10.0, July 5, 2022

We made significant improvements to every aspect of the SaveToDB add-in for database developers and business users.

Here are the highlighted features added to SaveToDB 10:

Created the Tab Framework to help business users build high-quality applications independently.
Simplified the creation of dynamic analytic forms utilizing JSON features with stored procedures.
Enhanced security features of the SaveToDB Framework to allow hosting multiple applications in a single database.
Added online samples for MySQL, PostgreSQL, SQLite, and OData.
Implemented complete support for HTTP commands to enable REST API usage everywhere.
Added full support for Basic, Windows, Forms, OAuth1, and OAuth2 authentication schemes to load and save protected data using REST API.
Introduced a description task pane to load Excel table descriptions from a database.
Enabled the loading and saving of comments in a database.
Significantly improved reload performance for workbooks with many tables.
Enhanced user experience with automatic updates for dependent validation lists and parameter values.
Added an auto-update tool for end-users to check and install SaveToDB updates.

We applied existing feature improvements to SaveToDB versions 7, 8, and 9 as well.

We recommend updating to the latest versions at a minimum.

Feel free to upgrade to SaveToDB 10. Customers with an active upgrade warranty can do this for free.

Changes in End-User License Agreement

SaveToDB includes an updated End-User License Agreement.

The most important change is as follows:

"Consent to be included in the client list: By purchasing the software on behalf of your company, you implicitly consent to the listing of your company name as our customer. You can revoke this consent at any time by submitting a request."

SaveToDB Personal edition is only available under an active upgrade warranty. New purchases of SaveToDB Personal are not available.

Breaking Changes

SaveToDB versions 7.31, 8.26, and 9.12 also include the following changes. No additional steps are required when upgrading from these versions.

The add-in adds null values to parameter value lists prepared by stored procedures or SQL queries.
This feature eliminates the need to use rows like SELECT NULL AS id, NULL AS name UNION ALL in your SQL code to get such values.
It also allows obtaining lists of parameter and cell values using the same procedures. After the update, you may need to add the _NotNull value to the TARGET_WORKSHEET field for ParameterValues handlers.
See the Developer Guide for details.
We changed the formats of connection strings and authorization data for connecting to web data and text files.
This change relates to new opportunities for working with the REST API and authorization using OAuth1 and OAuth2 for any provider.
The new version also allows using connection and authorization settings from databases.
After updating the add-in, you should update the data and configuration for such requests.
New connection and authorization data do not work in versions prior to 7.31, 8.26, and 9.12.
Therefore, after testing the update, we recommend updating to the newest version for all users.
We put significant effort into testing all the features. SaveToDB 9.12 is the most tested version.

New Features

SaveToDB 10 is now available in Portuguese, Simplified Chinese, Traditional Chinese, Japanese, and Korean.
The add-in supports language codes up to 10 characters.
For example, you can use zh-cn, zh-hans, and zh-hans-cn. zh-hans and zh-hant are preferable for Chinese.
The add-in includes an AutoUpdate tool to check for and install updates. To run it manually, choose Help > Check for Updates to launch the wizard. The check request does not contain personal data. However, we can identify the license owner in internal systems. We use this information to count the current licenses more accurately and can provide this information to the owner upon request. This feature is useful for companies with a large number of users and frequent computer replacements. You can disable update checking in the utility dialog box if you do not agree with this statement.
The add-in features redesigned Database Connection Wizard, Web Data Connection Wizard, and Text File Connection Wizard instead of a single Data Connection Wizard.
The Application Installer wizard now includes SaveToDB Framework 10.
SaveToDB Framework 10 has new views to select configuration settings, checking actual user permissions on schema objects. It also introduces a new view, xls.users, allowing business users to manage roles, users, and permissions from the Excel context menu.
The Application Installer wizard includes the Tab Framework.
This framework enables developers and business users to create and use high-quality database applications with Microsoft Excel. It features user-friendly tables for configuring advanced features of the SaveToDB add-in.
The Online Samples menu now includes new samples for MySQL, PostgreSQL, SQLite, and OData.
The add-in detects object dependencies and updates dependent objects when saving changes to master objects.
Developers can use DependsOn and DoNotAddDependsOn handlers to configure object dependencies manually.
The add-in supports a new type of dynamic form based on JSON. Stored procedures can return JSON with collections: parameters, columns, rows, and cells. The add-in creates a two-dimensional table instead, correctly supporting saving changes and cell change handlers. Developers must mark such procedures with the JsonForm handler. You can learn more about the SaveToDB Framework for Dynamic Tables built on this feature.
The add-in includes a new description task pane. This task pane displays values from the TRANSLATED_NAME, TRANSLATED_DESC, and TRANSLATED_COMMENT columns of the translation tables and views. This feature enables the creation of dynamic language-dependent descriptions of database objects for business users.
The add-in saves and restores cell comments. Users can enable or disable this feature using the SaveToDB Options dialog box. Developers can control this feature using the KeepComments and DoNotKeepComments handlers. Additionally, developers can specify a column used to load and save comments in a database.
The cell change handlers can use the @comment variable to access cell comments.
Developers can explicitly define objects used to load and save table formats using the LoadFormat and SaveFormat handlers.
The Web Data Connection Wizard allows customizing OAuth1 and OAuth2 authentication options.
The Database Connection Wizard now includes a new page for authenticating HTTP queries. For example, developers can configure HTTP queries in the xls.objects table. The add-in will prompt for credentials when a user connects to a web data source for the first time.
The add-in supports WHERE and ORDER BY clauses for web and file queries internally. Users and developers can easily load data from the web and files using commands like: ` SELECT <fields> FROM <url> [WHERE <conditions>] [ORDER BY <columns>] SELECT <fields> FROM <filename> [WHERE <conditions>] [ORDER BY <columns>]


The add-in allows using HTTP commands of any type, including GET, POST, PUT, PATCH, and DELETE, in configured objects and handlers. Developers can configure REST objects to connect and REST API calls to save changes and handle events.

The add-in allows naming worksheets with translated names of inserted objects. Use _UseTranslatedName in the TARGET_WORKSHEET columns of the handler configurations and UseTranslatedName in the DEFINITION` columns of the workbook configurations.
