# Importing Excel binary workbooks
|
|
|
|
Open an `.xlsb` file with File → Open, drag it onto GridCraft, or pass it to the CLI.
|
|
GridCraft imports worksheet data into a new workbook and shows the conversion limits.
|
|
|
|
The import reads worksheet names, visibility, numbers, text, booleans, errors and merged
|
|
cells. Formula cells become their **last saved results**, not live formulas. Those results
|
|
may be out of date if the source application did not recalculate before saving.
|
|
|
|
Source formatting is omitted: dates, times, percentages and currencies initially display as
|
|
their underlying numbers. The workbook's date system is retained. Charts, images, names,
|
|
macros and other workbook features are not imported. GridCraft does not write XLSB files.
|
|
|
|
Save opens Save As and suggests a new `.xlsx` file. The source XLSB file is not used as the
|
|
workbook's save destination; requests to save to `.xlsb` return an error.
|
|
|
|
```sh
|
|
gridcraft-cli info source.xlsb
|
|
gridcraft-cli convert source.xlsb imported.xlsx
|
|
```
|
|
|
|
CLI import warnings go to stderr, leaving structured output on stdout available for scripts.
