=CHECK(your_workbook.xlsm)
Have an Excel file you can't leave behind?
Drop it here. SumOffice tells you what works, what doesn't, and what your workbook depends on — before you switch.
What you get, in seconds
| Verdict | One of the four words our Compatibility Center uses about a workbook's macros:
NativeSumSheet can attempt to run them in its own sandbox
Migrationwaits for work on our queue
Excel bridgestays in Excel by design
Preserve onlysource we could not classify — kept byte for byte
|
|---|---|
| Formulas | How many, how many distinct functions, and how many of them the engine knows by name — with the unknown ones listed. Nested forms are checked by opening the workbook; the “Open it” button is that test. |
| Data logic | PivotTables, Power Query, external links, connections, charts, tables. |
| Macros | How many macros Excel would offer you, how many of them route native, every entry point with its route, what blocks the rest (events, external automation, COM components, UserForms, libraries). |
| Open it | The same workbook opened in SumOffice, in your browser, on our server — the real engine, the real file. |
Every number says what it counts
Percentages are written as “N of M”, never alone. A route describes what we cover today, not a promise that a macro behaves as in Microsoft Excel; only a recorded run against Excel says that. Missing evidence is not proof of absence: a file we could not read is reported as unreadable, not as “no macros”.
Calibration, so you know what these words mean on real files: on the public Enron corpus — 3 738 macro workbooks, 13 870 macros a person can start — 73 % of the macros route native, 18 % wait for work on our queue, 8 % stay in Excel by design. Read, not run.
What happens to your file
- It is stored on one server, read three times (package structure, formula names, VBA source), and deleted after 24 hours or sooner.
- Nothing in it is executed — no macro, no query, no external connection.
- It is not copied to storage, analytics or third parties. If you leave an address, we write to you about this file and nothing else.
Regular work with your workbooks — editing, saving back, macros running — is the SumSheet app (Windows, macOS, Linux, Android, iOS) and the SumSheet view-SDK for your own products; see Capabilities and Developers.
