Frequently asked questions
About formats, about the calculation, about what leaves the tab, and about what the tool refuses to do.
- How do I open an .mpp file without Microsoft Project?
- Ask whoever sends it for an XML export: in Project, File, Save As, XML format. That XML opens here in full. The .mpp itself is recognised and inventoried, but its detail is not read yet. The .mpp page.
- Why do you not read the .mpp in full?
- The .mpp is not a published format, and its internal layout has changed with every version of Project since 1998. Writing a reader without a body of real files gives a tool that gets things wrong silently. Until that body exists, the tool says what it knows and what it does not.
- Is it free?
- Using the site is free, with no account and nothing in return. Only one thing is sold: the package to install on an internal network.
- Is my schedule sent anywhere?
- No. The page is not allowed to open a connection to another site, and the browser is what enforces that. How to check it.
- Does the recalculation give the same dates as Project?
- On the test files the agreement is complete to the minute. That is not a general guarantee, and the tool does not offer one: the file's dates and the recalculated dates are shown side by side, with the gap task by task.
- Why a one-minute tolerance?
- Project stores its dates to the second (13:42:24) while the engine works in whole minutes. Without a tolerance, a perfectly matching schedule would show as divergent. Strict comparison to the second is still available.
- Can I hand the file back to someone who has Project?
- Yes: the workshop writes a Microsoft Project XML, which Project opens natively. It never writes an .mpp.
- Does Klargantt level resources?
- No. An overload is reported, never resolved on your behalf. Moving a task to smooth a workload is a management decision, not a calculation.
- Does the quality check say whether my schedule is compliant?
- No. It gives, point by point, the number, the threshold and the tasks concerned, with four verdicts: met, exceeded, to be stated, not applicable. The conclusion belongs to whoever signs.
- Is there a size limit?
- The limit is your browser's memory. A schedule of several thousand tasks is read and recalculated in under a second.
- Does it work on Mac, on Linux, on a tablet?
- Yes. There is nothing to install: it is a web page, and all the work happens in the browser.
- Does it work without a connection?
- Yes, after a first visit. The site installs itself to work offline, which is also the best way to check that nothing leaves.
