What is a .XLTM file?
Everything worth knowing about Microsoft Excel Macro-Enabled Workbook Template files.
An XLTM file is a Microsoft Excel macro-enabled workbook template. Opening it creates a new unnamed .xlsm workbook with the template's formatting, formulas, and VBA macros already loaded, and the original template stays untouched. Microsoft Excel is the only application that fully supports the VBA macros inside; LibreOffice Calc can open the sheet data but macro execution is limited. To get an editable workbook, open the file in Excel and save it as XLSM.

Is my .XLTM file uploaded anywhere?
No. Your .XLTM file is opened for you.
Are formulas recalculated?
The viewer shows the values Excel or LibreOffice saved in the file, plus the formula behind each cell when you click it. It doesn't recalculate, so what you see is exactly what the author saw when saving.
Can I open a password-protected .XLTM file?
Not yet. Files encrypted with a password to open are detected and reported; sheets that are only "protected against editing" open normally.
Why doesn't my chart or image show?
This viewer focuses on cell data: values, formulas, merged cells and fill colours. Charts, images and pivot table layouts are not drawn yet.
How big a file can I open?
Up to 50 MB. Large sheets are shown 500 rows at a time so your browser stays fast. Search still covers every row.
