## Integration Details
|
||||
:::info
|
||||
|
||||
All operations must be run from Go code. This example passes Base64 strings.
|
||||
|
||||
:::caution
|
||||
|
||||
Wails currently does not provide the equivalent of NodeJS `fs` module. All raw
|
||||
file operations must be performed in Go code.
|
||||
|
||||
The HTML File Input Element does not show a file picker. This is a known bug.
|
||||
The demo works around the issue by showing pickers in Go code.
|
||||
This demo assumes some familiarity with JavaScript and with Go. If you would
|
||||
prefer a pure JavaScript solution, the [Electron](/docs/demos/desktop/electron)
|
||||
platform provides many native features out of the box.
|
||||

|
||||
|
||||
## Integration Details
|
||||
|
||||
The [SheetJS NodeJS Module](/docs/getting-started/installation/nodejs) can be
|
||||
installed in the `frontend` folder and imported in frontend scripts.
|
||||
|
||||
:::caution
|
||||
|
||||
Wails currently does not provide the equivalent of NodeJS `fs` module.
|
||||
|
||||
Reading and writing raw file data must be implemented in native Go code.
|
||||
|
||||
:::
|
||||
|
||||
This demo includes native Go code for showing dialogs and reading and writing
|
||||
files. When sending data between Go and JavaScript code, the raw files are
|
||||
encoded as Base64 strings.
|
||||
|
||||
### Reading Files
|
||||
|
||||
The file picker and reading operations can be combined in one Go function.
|
||||
When the user clicks the "Import File" button, the frontend tells the Go backend
|
||||
to read data. The user will be presented with a file picker to select a file to
|
||||
read. The Go backend will read the data, encode as a Base64 string, and send the
|
||||
result to the frontend.
|
||||
|
||||
The frontend will parse the data using the SheetJS `read` method[^2], generate
|
||||
HTML tables with `sheet_to_html`[^3], and display the tables on the frontend.
|
||||

||||

2) Generate the file data in JS, pass the data back to Go
|

:::
|

|

3) Write to file in Go

When the user clicks the "Export File" button, the frontend asks the Go backend
|
||||
for the output filename and path. The user will be presented with a file picker
|
||||
to select the output folder and workbook type. The backend will send the name
|
||||
to the frontend.
|
||||
|
||||
The frontend will generate a workbook object from the table using the SheetJS
|
||||
`table_to_book` method[^9]. The SheetJS `write` method[^10] will generate a
|
||||
Base64 string from the data.
|
||||
|
||||
The frontend will send the Base64 string to the backend. The backend will write

the data to a file in the selected folder.

QuickJS is an embeddable JS engine written in C. It provides a separate set of
|
||||
functions for interacting with the filesystem and the global object. It can run
|
||||
the standalone browser scripts.
|
||||
[QuickJS](https://bellard.org/quickjs/) is an embeddable JS engine written in C.
|
||||
It has built-in support for reading and writing file data stored in memory.
|
||||
|
||||
The [Standalone scripts](/docs/getting-started/installation/standalone) can be
|
||||
parsed and evaluated in a QuickJS context.
|
||||
[SheetJS](https://sheetjs.com) is a JavaScript library for reading and writing
|
||||
data from spreadsheets.
|
||||
|
||||
This demo uses QuickJS and SheetJS to pull data from a spreadsheet and print CSV
|
||||
rows. We'll explore how to load SheetJS in a QuickJS context and process
|
||||
spreadsheets from C programs.
|
||||
|
||||
The ["Integration Example"](#integration-example) section includes a complete
|
||||
command-line tool for reading data from files.

_Initialize QuickJS_
|
||||
:::note
|
||||
|
||||
Many QuickJS functions are not documented. The explanation was verified against
|
||||

||||
### Initialize QuickJS
|
||||
|
||||
Most QuickJS API functions interact with a `JSContext` object[^1], which is
|
||||
normally created with `JS_NewRuntime` and `JS_NewContext`:
|
||||
|
||||
```c
|
||||
#include "quickjs.h"
|
||||
|
||||
/* initialize context */
|
||||
JSRuntime *rt = JS_NewRuntime();
|
||||
JSContext *ctx = JS_NewContext(rt);
|
||||
```
|
||||
|
||||
QuickJS provides a `global` object through `JS_GetGlobalObject`:
|
||||
|
||||
```c
|
||||
/* initialize */
|
||||
JSRuntime *rt = JS_NewRuntime();
|
||||
JSContext *ctx = JS_NewContext(rt);
|
||||
|
||||
/* obtain reference to global object */
|
||||
JSValue global = JS_GetGlobalObject(ctx);

|
||||
<details><summary><b>Cleanup</b> (click to show)</summary>
|
||||
|
||||
/* free after use */
|
||||
Once finished, programs are expected to cleanup by using `JS_FreeValue` to free
|
||||
values, `JS_FreeContext` to free the context pointer, and `JS_FreeRuntime` to
|
||||
free the runtime:
|
||||
|
||||
```c
|
||||
/* global is a JSValue */
|
||||
JS_FreeValue(ctx, global);
|
||||
|
||||
/* cleanup */

_Load SheetJS Scripts_
|
||||
[SheetJS Standalone scripts](/docs/getting-started/installation/standalone) can

|
||||
|
||||
The main library can be loaded by reading the script from the file system and
|

|
||||
```
|
||||
|
||||
To confirm the library is loaded, `XLSX.version` can be inspected:
|
||||
If the library is loaded, `XLSX.version` will be a string. This string can be
|
||||
pulled into the main C program.
|
||||

1) Get the `XLSX` property of the global object using `JS_GetPropertyStr`:

JSValue XLSX = JS_GetPropertyStr(ctx, global, "XLSX");

JSValue version = JS_GetPropertyStr(ctx, XLSX, "version");

|
||||
size_t vlen; const char *vers = JS_ToCStringLen(ctx, &vlen, version);

The `ArrayBuffer` will be parsed with the SheetJS `read` method[^2]. The CSV row
|
||||
data will be generated with `sheet_to_csv`[^3].
|
||||
|
||||
#### Parse the ArrayBuffer
|
||||
|
||||
:::note pass
|
||||
|
||||
The goal is to run the equivalent of the following JavaScript code:
|
||||
|
||||
```js
|
||||
/* `ab` is the `ArrayBuffer` from the previous step */
|
||||
var wb = XLSX.read(ab);
|
||||
```
|
||||
|
||||
:::
|
||||
|
||||
1) Get the `XLSX` property of the global object and the `read` property of `XLSX`:
|
||||
|
||||
```c
|
||||
/* obtain reference to XLSX.read */
|
||||
JSValue XLSX = JS_GetPropertyStr(ctx, global, "XLSX");
|
||||
|
||||
/* call XLSX.read(ab) */
|
||||
JSValue XLSX_read = JS_GetPropertyStr(ctx, XLSX, "read");
|
||||
```
|
||||
|
||||
2) Create an array of arguments to pass to the function. In this case, the
|
||||
`read` function will be called with one argument (`ArrayBuffer` data):
|
||||
|
||||
```c
|
||||
/* prepare arguments */
|
||||
JSValue args[] = { ab };
|
||||
```
|
||||
|
||||
3) Use `JS_Call` to call the function with the arguments:
|
||||
|
||||
```c
|
||||
/* call XLSX.read(ab) */
|
||||
JSValue wb = JS_Call(ctx, XLSX_read, XLSX, 1, args);
|
||||
```
|
||||
|
||||
#### Get First Worksheet
|
||||
|
||||
:::note pass
|
||||
|
||||
The goal is to get the first worksheet. In JavaScript, the `SheetNames` property
|
||||
of the workbook is an array of strings and the `Sheets` property holds worksheet
|
||||
objects[^4]. The desired action looks like:
|
||||
|
||||
```js
|
||||
/* `wb` is the workbook from the previous step */
|
||||
var wsname = wb.SheetNames[0];
|
||||
var ws = wb.Sheets[wsname];
|
||||
```
|
||||
|
||||
:::
|
||||
|
||||
4) Pull `wb.SheetNames[0]` into a C string using `JS_GetPropertyStr`:
|
||||
|
||||
```c
|
||||
/* get `wb.SheetNames[0]` */
|
||||
JSValue SheetNames = JS_GetPropertyStr(ctx, wb, "SheetNames");
|
||||
JSValue Sheet1 = JS_GetPropertyStr(ctx, SheetNames, "0");
|
||||
|
||||
/* pull first sheet name into C code */
|
||||
size_t wslen; const char *wsname = JS_ToCStringLen(ctx, &wslen, Sheet1);
|
||||
```
|
||||
|
||||
5) Get the worksheet object:
|
||||
|
||||
```c
|
||||
/* get wb.Sheets[wsname] */
|
||||
JSValue Sheets = JS_GetPropertyStr(ctx, wb, "Sheets");
|
||||
JSValue ws = JS_GetPropertyStr(ctx, Sheets, wsname);
|
||||
```
|
||||
|
||||
#### Convert to CSV
|
||||
|
||||
:::note pass
|
||||
|
||||
The goal is to call `sheet_to_csv`[^5] and pull the result into C code:
|
||||
|
||||
```js
|
||||
/* `ws` is the worksheet from the previous step */
|
||||
var csv = XLSX.utils.sheet_to_csv(ws);
|
||||
```
|
||||
|
||||
:::
|
||||
|
||||
6) Create a references to `XLSX.utils` and `XLSX.utils.sheet_to_csv`:
|
||||
|
||||
```c
|
||||
/* obtain reference to XLSX.utils.sheet_to_csv */
|
||||
JSValue utils = JS_GetPropertyStr(ctx, XLSX, "utils");
|
||||
JSValue sheet_to_csv = JS_GetPropertyStr(ctx, utils, "sheet_to_csv");
|
||||
```
|
||||
|
||||
7) Create arguments array:
|
||||
|
||||
```c
|
||||
/* prepare arguments */
|
||||
JSValue args[] = { ws };
|
||||
```
|
||||
|
||||
8) Use `JS_Call` to call the function and use `JS_ToCStringLen` to pull the CSV:
|
||||
|
||||
```c
|
||||
JSValue csv = JS_Call(ctx, sheet_to_csv, utils, 1, args);
|
||||
size_t csvlen; const char *csvstr = JS_ToCStringLen(ctx, &csvlen, csv);
|
||||
```
|
||||
|
||||
At this point, `csvstr` is a C string that can be printed to standard output.

export const g = {style: {backgroundColor:"green"}};
|
||||
|
||||
Each cell in a worksheet has a unique address which specifies the row and the
|
||||
column that include the cell.
|
||||
|
||||
## Basic Concepts
|
||||
|
||||
### Rows
|
||||
|
||||
Spreadsheet applications typically display ordinal row numbers, where `1` is the
|
||||
first row, `2` is the second row, etc. The numbering starts at `1`.
|
||||
|
||||
SheetJS follows JavaScript counting conventions, where `0` is the first row, `1`
|
||||
is the second row, etc. The numbering starts at `0`.
|
||||
|
||||
The following table lists some example row labels:
|
||||
|
||||
| Ordinal | Row Label | SheetJS |
|
||||
|:----------|----------:|----------:|
|
||||
| First | `1` | `0` |
|
||||
| Second | `2` | `1` |
|
||||
| 26th | `26` | `25` |
|
||||
| 420th | `420` | `419` |
|
||||
| 7262nd | `7262` | `7261` |
|
||||
| 1048576th | `1048576` | `1048575` |
|
||||
|
||||
### Columns
|
||||
|
||||
Spreadsheet applications typically use letters to represent columns.
|
||||
|
||||
The first column is `A`, the second column is `B`, and the 26th column is `Z`.
|
||||
After `Z`, the next column is `AA` and counting continues through `AZ`. After
|
||||
`AZ`, the count continues with `BA`. After `ZZ`, the count continues with `AAA`.
|
||||
|
||||
Some sample values, along with SheetJS column indices, are listed below:
|
||||
|
||||
| Ordinal | Column Label | SheetJS |
|
||||
|:--------|:-------------|--------:|
|
||||
| First | `A` | `0` |
|
||||
| Second | `B` | `1` |
|
||||
| 26th | `Z` | `25` |
|
||||
| 27th | `AA` | `26` |
|
||||
| 420th | `PD` | `419` |
|
||||
| 702nd | `ZZ` | `701` |
|
||||
| 703rd | `AAA` | `702` |
|
||||
| 7262nd | `JSH` | `7261` |
|
||||
| 16384th | `XFD` | `16383` |
|
||||
|
||||
## Cell Addresses
|
||||
|
||||
### A1-Style
|
||||
|
||||
A1-Style is the default address style in Lotus 1-2-3 and Excel.
|
||||
|
||||
A cell address is the concatenation of column label and row label.
|
||||
|
||||
For example, the cell in the third column and fourth row is `C4`, concatenating
|
||||
the third column label (`C`) and the fourth row label (`4`)
|
||||
|
||||
### SheetJS Cell Address
|
||||
|
||||
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 Ranges
|
||||
|
||||
### A1-Style
|
||||
|
||||
A cell range is represented as the top-left cell of the range, followed by `:`,
|
||||
followed by the bottom-right cell of the range. For example, the range `"C2:D4"`
|
||||
includes the 6 green cells in the following table:
|
||||
|
||||
<table><tbody>
|
||||
<tr><th> </th><th>A</th><th>B</th><th>C</th><th>D</th><th>E</th></tr>
|
||||
<tr><th>1</th><td> </td><td> </td><td> </td><td> </td><td> </td></tr>
|
||||
<tr><th>2</th><td> </td><td> </td><td {...g}></td><td {...g}></td><td> </td></tr>
|
||||
<tr><th>3</th><td> </td><td> </td><td {...g}></td><td {...g}></td><td> </td></tr>
|
||||
<tr><th>4</th><td> </td><td> </td><td {...g}></td><td {...g}></td><td> </td></tr>
|
||||
<tr><th>5</th><td> </td><td> </td><td> </td><td> </td><td> </td></tr>
|
||||
</tbody></table>
|
||||
|
||||
A column range is represented by the left-most column, followed by `:`, followed
|
||||
by the right-most column. For example, the range `C:D` represents the third and
|
||||
fourth columns.
|
||||
|
||||
A row range is represented by the top-most row, followed by `:`, followed by the
|
||||
bottom-most column. For example, `2:4` represents the second/third/fourth rows.
|
||||
|
||||
### SheetJS Range
|
||||
|
||||
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}}`.

# Common Spreadsheet Address Styles
|
||||
## Utilities
|
||||
|
||||
## A1-Style
|
||||
|
||||
A1-Style is the default address style in Lotus 1-2-3 and Excel.
|
||||
|
||||
Columns are specified with letters, counting from `A` to `Z`, then `AA` to `ZZ`,
|
||||
then `AAA`. Some sample values, along with SheetJS column indices, are listed:
|
||||
|
||||
| Ordinal | `A1` | SheetJS |
|
||||
|:--------|:--------|--------:|
|
||||
| First | `A` | `0` |
|
||||
| Second | `B` | `1` |
|
||||
| 26th | `Z` | `25` |
|
||||
| 27th | `AA` | `26` |
|
||||
| 702nd | `ZZ` | `701` |
|
||||
| 703rd | `AAA` | `702` |
|
||||
| 16384th | `XFD` | `16383` |
|
||||
|
||||
Rows are specified with numbers, starting from `1` for the first row. SheetJS
|
||||
APIs that take row indices start from `0` (ECMAScript convention).
|
||||
|
||||
A cell address is the concatenation of column text and row number. For example,
|
||||
the cell in the third column and fourth row is "C4".
|
||||
|
||||
A cell range is represented as the top-left cell of the range, followed by `:`,
|
||||
followed by the bottom-right cell of the range. For example, the range `"C2:D4"`
|
||||
includes 6 cells marked with ▒ in the table below:
|
||||
|
||||
<table><tbody>
|
||||
<tr><th> </th><th>A</th><th>B</th><th>C</th><th>D</th><th>E</th></tr>
|
||||
<tr><th>1</th><td> </td><td> </td><td> </td><td> </td><td> </td></tr>
|
||||
<tr><th>2</th><td> </td><td> </td><td>▒</td><td>▒</td><td> </td></tr>
|
||||
<tr><th>3</th><td> </td><td> </td><td>▒</td><td>▒</td><td> </td></tr>
|
||||
<tr><th>4</th><td> </td><td> </td><td>▒</td><td>▒</td><td> </td></tr>
|
||||
<tr><th>5</th><td> </td><td> </td><td> </td><td> </td><td> </td></tr>
|
||||
</tbody></table>
|
||||
|
||||
A column range is represented by the left-most column, followed by `:`, followed
|
||||
by the right-most column. For example, the range `C:D` represents the third and
|
||||
fourth columns.
|
||||
|
||||
A row range is represented by the top-most row, followed by `:`, followed by the
|
||||
bottom-most column. For example, `2:4` represents the second/third/fourth rows.
