Convert, rebuild, check

The whole workbook, in one go, with the proof in the file.
  1. A

    Convert

    Every formula in the workbook. The ones the other product writes differently are rewritten, including the ones that would quietly give a different answer.

    =SORT(A2:B9,1,-1) → =SORT(A2:B9,1,FALSE)In Excel, -1 sorts descending; Google Sheets would sort ascending.
  2. B

    Rebuild

    Values, formulas and the look of the workbook come along. A cell that can't be converted keeps its value, so everything that depends on it still works.

    • number formats
    • merged cells
    • frozen rows
    • conditional formatting
    • dropdowns
    • charts
    • filters
    • comments
  3. C

    Check

    Every converted cell is compared with the value the original calculated. The file checks itself: open it, and its Report tab tells you how many cells match.

Who it's for

  • Your company is switching

    Microsoft 365 to Google Workspace, or back. Your models, budgets and trackers have to keep working on the other side.

  • A client sent the other format

    They work in Excel, you deliver in Google Sheets, or the other way round, and the numbers have to match theirs.

  • Finance models with real money in them

    Long formula chains, circular references, many sheets. A wrong number nobody notices is the expensive kind.

The same formula, a different answer

Some formulas give a different result in each product, with no error to warn you. SheetSure rewrites each one so the numbers stay the same.

What doesn't convert

Said plainly, before you upload. The report lists every one of these, cell by cell.
No equivalent

Things only one product can do

Links to other workbooks, web lookups (WEBSERVICE), data cubes, What-If tables. These cells keep their value, so formulas that read them still work.

Redo by hand

Possible in the other product, but written differently

A few things the other product can do, just differently, such as a custom function you defined yourself. The report says what to recreate.

Not migrated

Left out of the file

Pivot tables, images, macros, data bars, icon sets, dropdowns that grow with a list, chart trendlines. The Report tab lists any your workbook has.
