## Common Spreadsheet Format
|
||
|
|
|
||
|
|
SheetJS conforms to the Common Spreadsheet Format (CSF):
|
||
|
|
|
||
|
|
### General Structures
|
||
|
|
|
||
|
|
Cell address objects are stored as `{c:C, r:R}` where `C` and `R` are 0-indexed
|
||
|
|
column and row numbers, respectively. For example, the cell address `B5` is
|
||
|
|
represented by the object `{c:1, r:4}`.
|
||
|
|
|
||
|
|
Cell range objects are stored as `{s:S, e:E}` where `S` is the first cell and
|
||
|
|
`E` is the last cell in the range. The ranges are inclusive. For example, the
|
||
|
|
range `A3:B7` is represented by the object `{s:{c:0, r:2}, e:{c:1, r:6}}`.
|
||
|
|
Utility functions perform a row-major order walk traversal of a sheet range:
|
||
|
|
|
||
|
|
```js
|
||
|
|
for(var R = range.s.r; R <= range.e.r; ++R) {
|
||
|
|
for(var C = range.s.c; C <= range.e.c; ++C) {
|
||
|
|
var cell_address = {c:C, r:R};
|
||
|
|
/* if an A1-style address is needed, encode the address */
|
||
|
|
var cell_ref = XLSX.utils.encode_cell(cell_address);
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
