🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Keep folders out of names supplied with bytes.
If file.open receives {"name":"uploads/book.xlsx","base64":...}, this assignment keeps uploads in source_path. CELL("filename") then returns uploads/[book.xlsx]Sheet1, although no file was opened from that folder. Store the name’s final path component for the byte-open branch. Use Path::file_name so the host path rules remain intact.

Rebased onto current |
It returned an empty string for every workbook, saved or not, so the classic
sheet-name formula `MID(CELL("filename",A1),FIND("]",…)+1,31)` gave #VALUE!:
with no `]` in the string there is nothing for FIND to find. Excel returns
`<folder>\[<file>]<sheet>`, and empty only before the first save.
The model had no file to report. `source_dir` could not serve: it names the
folder relative links to other workbooks are relative to, and must keep naming
it after a Save As into another folder, because the links held in memory are
still written for the old one — only the saved copy is rebased. `source_path`
is therefore its own field, with that distinction written down.
It is set when a workbook is opened, from the path made absolute so the folder
is the one the user sees, and when a full-fidelity save makes a file the
document's own — before the `saved` snapshot, or the workbook would read as
dirty the moment it was saved, and only when it changes, so an ordinary Save
does not clone the workbook for nothing. A workbook that arrived as bytes knows
its name but never a folder and reports `[name]Sheet`, which still splits on the
`]`; an import reports the file it came from, as Excel does. The sheet is the one
the reference is on, not the active one.
CELL is volatile and already in the volatile sets, so a cell holding it answers
from the next recalculation; after a Save As that means F9 rather than the save
itself, which the engine test asserts rather than papers over. Making a save
recalculate is a larger decision than this issue.
`check` still skips CELL("filename") as volatile, as docs/cli.md says: the
cached value in a file is the folder of the machine that saved it.

savemutatesd.wb.source_pathdirectly and does not use the stagededit/commitpath. The guideline requires direct-mutation commands to preserve recalculation and history semantics explicitly.

The other half of #1489. The German info types are #1502; this is
CELL("filename")itself, which returned an empty string for every workbook, saved or not.The bug
That middle formula is the classic way to put a sheet's name in a cell, and @KNUFFIXX measured it in 83 of 400 real German workbooks. With no
]in the string,FINDfails and the cell shows#VALUE!.Excel returns
<folder>\[<file>]<sheet>, and empty only for a workbook that has never been saved.Why it was empty
The workbook model had no file to report.
source_direxists, but it is there for a different job: it names the folder that relative links to other workbooks are relative to. It must not be updated on a Save As into another folder, because the links held in memory are still written for the old one — only the saved copy is rebased. So it could not be reused here, and overwriting it would have broken linked workbooks on the second save.Workbook::source_pathis therefore its own field, with that distinction written down where someone will meet it. It is set in two places:[name]Sheetwith none, which still splits on the]. An import reports the file it came from, as Excel does, even though Save must still ask where to put the.xlsx.savedsnapshot, or the workbook would read as dirty the moment it was saved, and only when it actually changes, so an ordinary Save does not clone the workbook for nothing.CELL("filename")then builds the string withPath::join, so the separator is the platform's. The sheet is the one the reference is on, not the active one.One thing deliberately not changed
CELLis volatile and already in the volatile sets, so a cell holding it answers from the next recalculation. After a Save As that means F9, not the save itself — the test asserts exactly that rather than papering over it. Making a save recalculate the workbook is a bigger decision than this issue, and it belongs to whoever wants to take it.For the same reason
checkstill skipsCELL("filename")as volatile, asdocs/cli.mdsays: the cached value in the file is the folder on the machine that saved it. So this does not move the corpus mismatch count; #1502 is the half that does.Tests
cell_filename_names_the_workbook_file(calc) — empty with no file; the full<folder>/[<file>]<sheet>; both reported formulas; the sheet is the referenced one, through a second sheet; and the bytes case with no folder. It fails onmainwithleft: Text("").cell_filename_follows_the_file_the_workbook_lives_in(engine, native) — the whole path through real files in a temp dir: new workbook empty and the formula#VALUE!, Save As then naming the file and the formula giving the sheet name, a fresh session opening that path and agreeing, a Save As into another folder following the new file, the workbook not reading as dirty after either save, and an open from bytes.Gates

Cut from
main, not from #1502, since they are separate halves and this one touches the model and the engine as well. They change different lines ofcell_info, so only the append point incrates/calc/src/tests.rsoverlaps; whichever lands second needs that one trivial rebase. With both in,ZELLE("Dateiname";A1)reaches this arm and the German sheet-name formula works, which is what #1489 asked for.Summary by CodeRabbit
CELL("filename", reference)now reports the workbook’s folder and filename, along with the referenced sheet name, when a file path is available. It returns an empty string for unsaved workbooks.
