Expand description
This crate reads an xlsx file and transforms it into an internal representation (Model).
An xlsx is a zip file containing a set of folders and xml files. The IronCalc json structure mimics the relevant parts of the Excel zip.
Although the xlsx structure is quite complicated, it’s essentials regarding the spreadsheet technology are easier to grasp.
The simplest workbook folder structure might look like this:
docProps
app.xml
core.xml
_rels
.rels
xl
_rels
workbook.xml.rels
theme
theme1.xml
worksheets
sheet1.xml
calcChain.xml
styles.xml
workbook.xml
sharedStrings.xml
[Content_Types].xml
Note that more complicated workbooks will have many more files and folders. For instance charts, pivot tables, comments, tables,…
The relevant json structure in IronCalc will be:
{
"name": "Workbook1",
"defined_names": [],
"shared_strings": [],
"worksheets": [],
"styles": {
"num_fmts": [],
"fonts": [],
"fills": [],
"borders": [],
"cell_style_xfs": [],
"cell_styles" : [],
"cell_xfs": []
}
}
Note that there is not a 1-1 correspondence but there is a close resemblance.
