Webtool Updates and Releases
Below you fill find an archive of updates over the past few months with bug fix and update information.
Feb 21, 2020
- Improved visualization. You get an even better visual representation of your spreadsheets.
- Multilingual Highlighter and Protection Manager. The Highlighter, which is used to better understand formula patterns on specific worksheets, and the Protection Manager, with which cells and worksheets can be efficiently protected, now both work on every language of Excel. PerfectXL itself will still be in English.
- Powerful performance. We have invested a lot of time and energy into general improvements in speed, stability, and general performance.

Major back-end refactoring and clean-up:
- The storage model has been almost completely rewritten: it is now simpler, more flexible and (much) faster.
- Analyses now have a correct time-out when they are too complex or use too much memory.
- The Analysis Worker service is hardened so that even an abusive analysis can not stop the whole process.
- The Analysis Worker service can now perform up to three analyses simultaneously.
- The analysis process progress is now reported to the webbrowser via push technology.
- The majority of inspections were tested again with new test cases and then refined and improved. This results in more accurate findings and better problem descriptions.
- The analyzer often reported the same problem at different locations, over and over again. Where this was logical and feasible, we grouped those problems into just one risk.
- We started identifying risks in charts, user-defined names (“named ranges”) and pivot tables.
- Extracting VBA code from a spreadsheet file is now done with EPPlus instead of a Python script.
- The login procedure has been rewritten to enable logging in via SSO.
- All database calls are now asynchronous, so that the web server is not so heavily loaded.
- We have made preparations to facilitate the deployment of the entire application. There is still a bit more work needed to get this functional.
- Underlying packages (including GemBox) have been updated to the latest version.
- A few minor security improvements.
- Many other refactorings, speed improvements and bug fixes. The code is now in a state where we can add new functions much faster. And they are on their way!

Overall performance improvements and smaller bug fixes.

Dec 7, 2017
Frontend change: use one big JSON-object structure get all the info for the analyzed workbook at once. This means that we don’t need any additional requests when switching between tabs. Except for the formula breakdown. All messages for the specific risks come from the new West Wind / DotNetLiquid localization implementation.
Backend change: Use MessagePack for the storage of all information that is needed for the big JSON object. Many other smaller refactorings.
