**Simple Notes/Comments**: XLSX/M, XLSB, BIFF8 XLS (read only), XLML, ODS (read only)

Comments and Notes have evolved over the years. "Notes" (powered by VML) were

the original comments. "Comments" were added later.

|

**Threaded Comments**: XLSX/M, XLSB (read only)

Excel 365 introduced "Threaded Comments" which do not support rich text but do

allow users to "reply". The original "Comments" were renamed to "Notes".

var fmla_arr = XLSX.utils.sheet_to_formulae(ws);

|

|

`XLSX.utils.sheet_to_formulae` generates an array of commands that represent
|
||||
how a person would enter data into an application.
|
||||
|
||||
## Live Preview
|
||||
|
||||
After choosing a file, the demo will extract and display all formulae.
|
||||
|
||||
```jsx live
|
||||
function SheetJSFormulaPreview() {
|
||||
const [__html, setHTML] = React.useState("Select a file");
|
||||
|
||||
return ( <>
|
||||
<pre dangerouslySetInnerHTML={{ __html }}/>
|
||||

|

const wb = XLSX.read(await e.target.files[0].arrayBuffer());

var res = "";
|
||||
wb.SheetNames.forEach((n, idx) => {
|
||||
const ws = wb.Sheets[n];
|
||||
res += `<b>Sheet #${idx+1} (${n})</b>\n`;
|
||||
res += XLSX.utils.sheet_to_formulae(ws).join("\n") + "\n\n";
|
||||
});
|
||||
setHTML(res);
|
||||
}}/>
|
||||
</> );
|
||||
}
|
||||
```
|
||||
|
||||
## Cell Processing
|
||||
|
||||
Cells are analyzed in "row-major order" (starting from the first row).
|
||||
|
||||
#### Cells without formulae
|
||||
|
||||
Cells without formulae are written as `A1-cell-address=value`:
|
||||
|
||||
```
|
||||
A1=1 // A1 is the numeric value 1
|
||||
B1=TRUE // B1 is the logical value TRUE
|
||||
```
|
||||
|
||||
String literals are prefixed with a `'` in accordance with Excel:
|
||||
|
||||
```
|
||||
A5='A4+A3 // A5 is the string "A4+A3"
|
||||
```
|
||||
|
||||
#### Cells with formulae
|
||||
|
||||
Cells with formulae are written as `A1-cell-address=formula`:
|
||||
|
||||
```
|
||||
A5=A4+A3 // A5 is a cell with formula =A4+A3
|
||||
```
|
||||
|
||||
#### Array formulae
|
||||
|
||||
Array formulae are written as `A1-range=formula`. They do not include the
|
||||
displayed curly braces:
|
||||
|
||||
```
|
||||
A4:B4=A2:B2*A3:B3 // A4:B4 array formula {=A2:B2*A3:B3}
|
||||
```
|
||||
|
||||
Single-cell array formulae are written with single-cell ranges:
|
||||
|
||||
```
|
||||
C4:C4=SUM(A2:A3*B2:B3) // C4 array formula {=SUM(A2:A3*B2:B3)}
|
||||
```
|
||||
|
||||
## Demo
|
||||
|
||||
This example constructs a workbook including cells with no formulae, cells with
|
||||
normal formulae, single-cell array formulae and array formulae spanning ranges.
|
||||
|
||||
For verification, the button writes a workbook whose formulae can be inspected.
