[Stata](https://www.stata.com/) is a statistical software package. It offers a
|
||||
robust C-based extension system.
|
||||
|
||||
[SheetJS](https://sheetjs.com) is a JavaScript library for reading and writing
|
||||
data from spreadsheets.
|
||||
|
||||
This demo uses SheetJS to pull data from a spreadsheet for further analysis
|
||||
within Stata. We'll create a Stata native extension that loads the
|
||||
[Duktape](/docs/demos/engines/duktape) JavaScript engine and uses the SheetJS
|
||||
library to read data from spreadsheets and converts to a Stata-friendly format.

The demo will read [a Numbers workbook](https://sheetjs.com/pres.numbers) and
|
||||
generate variables for each column. A sample Stata session is shown below:

Stata has limited support for processing spreadsheets through the `import excel`
|
||||
command[^1]. At the time of writing, it lacked support for XLSB, NUMBERS, and
|
||||
other common spreadsheet formats.
|
||||
|
||||
SheetJS libraries help fill the gap by normalizing spreadsheets to a form that
|
||||
Stata can understand.
|
||||
|
||||
:::
|
||||
|
||||
## Integration Details
|
||||
|
||||
The current recommendation involves a native plugin that reads arbitrary files
|
||||
and generates clean XLSX files that Stata can import.
|
||||
|
||||
The extension function ultimately pairs the SheetJS `read`[^2] and `write`[^3]
|
||||
methods to read data from the old file and write a new file:
|
||||
|
||||
```js
|
||||
var wb = XLSX.read(original_file_data, {type: "buffer"});
|
||||
var new_file_data = XLSX.write(wb, {type: "array", bookType: "xlsx"});
|
||||
```
|
||||
|
||||
The extension function `cleanfile` will take one or two arguments:
|
||||
|
||||
`plugin call cleanfile, "pres.numbers"` will generate `sheetjs.tmp.xlsx` from
|
||||
the first argument (`"pres.numbers"`) and print instructions to load the file.
|
||||
|
||||
`plugin call cleanfile, "pres.numbers" verbose` will additionally print CSV
|
||||
contents of each worksheet in the workbook.

||||

||||

||||

|
||||
nbuf --> |C\nWrite File| nfile
|
||||
```
|
||||
|
||||
### C Extensions
|
||||
|
||||
Stata C extensions are shared libraries or DLLs that use special Stata methods
|
||||
for parsing arguments and returning values.
|
||||
|
||||
Arguments are passed to the `stata_call` function in the DLL.
|
||||
|
||||
`SF_display` and `SF_error` display text and error messages respectively.
|
||||
|
||||
### Duktape JS Engine
|
||||
|
||||
This demo uses the [Duktape JavaScript engine](/docs/demos/engines/duktape). The
|
||||
SheetJS + Duktape demo covers engine integration details in more detail.
|
||||
|
||||
The [SheetJS Standalone scripts](/docs/getting-started/installation/standalone)
|
||||
can be loaded in Duktape by reading the source from the filesystem.
|
||||
|
||||
## Complete Demo
|
||||
|
||||
:::info pass
|
||||
|
||||
This demo was tested in Windows x64. The path names and build commands will
|
||||
differ in other platforms and operating systems.
|
||||
|
||||
:::
|
||||
|
||||
The [`cleanfile.c`](pathname:///stata/cleanfile.c) extension defines one plugin
|
||||
function. It can be chained with `import excel`:
|
||||
|
||||
```stata
|
||||
program cleanfile, plugin
|
||||
plugin call cleanfile, "pres.numbers" verbose
|
||||
program drop cleanfile
|
||||
import excel "sheetjs.tmp.xlsx", firstrow
|
||||
```
|
||||
|
||||
### Create Plugin
|
||||
|
||||
0) Ensure "Windows Subsystem for Linux" (WSL) and Visual Studio are installed.
|
||||
|
||||
1) Open a new "x64 Native Tools Command Prompt" window and create a project
|
||||
folder `c:\sheetjs-stata`:
|
||||
|
||||
```powershell
|
||||
cd c:\
|
||||
mkdir sheetjs-stata
|
||||
cd sheetjs-stata
|
||||
```
|
||||
|
||||
2) Enter WSL:
|
||||
|
||||
```powershell
|
||||
bash
|
||||
```
|
||||
|
||||
3) Download [`stplugin.c`](https://www.stata.com/plugins/stplugin.c) and
|
||||
[`stplugin.h`](https://www.stata.com/plugins/stplugin.h) from the Stata website:
|
||||
|
||||
```bash
|
||||
curl -LO https://www.stata.com/plugins/stplugin.c
|
||||
curl -LO https://www.stata.com/plugins/stplugin.h
|
||||
```
|
||||
|
||||
4) Still within WSL, install Duktape:
|
||||
|
||||
```bash
|
||||
curl -LO https://duktape.org/duktape-2.7.0.tar.xz
|
||||
tar -xJf duktape-2.7.0.tar.xz
|
||||
mv duktape-2.7.0/src/*.{c,h} .
|
||||
```
|
||||
|
||||
5) Still within WSL, download the demo source
|
||||
[`cleanfile.c`](https://docs.sheetjs.com/stata/cleanfile.c):
|
||||
|
||||
```bash
|
||||
curl -LO https://docs.sheetjs.com/stata/cleanfile.c
|
||||
```
|
||||
|
||||
6) Exit WSL:
|
||||
|
||||
```bash
|
||||
exit
|
||||
```
|
||||
|
||||
The window will return to the command prompt.
|
||||
|
||||
7) Build the DLL:
|
||||
|
||||
```powershell
|
||||
cl /LD cleanfile.c stplugin.c duktape.c
|
||||
```
|
||||
|
||||
### Install Plugin
|
||||
|
||||
8) Copy the DLL to `cleanfile.plugin` in the Stata data directory. For example,
|
||||
with a shared data directory `c:\data`:
|
||||
|
||||
```powershell
|
||||
mkdir c:\data
|
||||
copy cleanfile.dll c:\data\cleanfile.plugin
|
||||
```
|
||||
|
||||
### Download SheetJS Scripts
|
||||
|
||||
9) Move to the `c:\data` directory
|
||||
|
||||
```powershell
|
||||
cd c:\data
|
||||
```
|
||||
|
||||
10) Enter WSL
|
||||
|
||||
```powershell
|
||||
bash
|
||||
```
|
||||
|
||||
11) Within WSL, download SheetJS scripts and the test file.
|
||||
|
||||
<CodeBlock language="bash">{`\
|
||||
curl -LO https://cdn.sheetjs.com/xlsx-${current}/package/dist/shim.min.js
|
||||
curl -LO https://cdn.sheetjs.com/xlsx-${current}/package/dist/xlsx.full.min.js
|
||||
curl -LO https://sheetjs.com/pres.numbers`}
|
||||
</CodeBlock>
|
||||
|
||||
12) Exit WSL:
|
||||
|
||||
```bash
|
||||
exit
|
||||
```
|
||||
|
||||
The window will return to the command prompt.
|
||||
|
||||

||||
|
||||

|
||||
The screenshot in the introduction shows the result of steps 13 - 19
|
||||
|
||||
:::
|
||||
|
||||
13) Open Stata
|
||||
|
||||
14) Move to the `c:\data` directory in Stata:
|
||||
|
||||
```stata
|
||||
cd c:\data
|
||||
```
|
||||
|
||||
15) Load the `cleanfile` plugin:
|
||||
|
||||
```stata
|
||||
program cleanfile, plugin
|
||||
```
|
||||
|
||||
16) Read the `pres.numbers` test file:
|
||||
|
||||
```stata
|
||||
plugin call cleanfile, "pres.numbers" verbose
|
||||
```
|
||||
|
||||
The result will show the data from `pres.numbers`:
|
||||
|
||||
<pre>
|
||||
<b>. plugin call cleanfile, "pres.numbers" verbose</b>{'\n'}
|
||||

|
||||
Donald Trump,45{'\n'}
|
||||

|
||||

|
||||
Saved to `sheetjs.tmp.xlsx`{'\n'}
|
||||
<span {...b}>import excel "sheetjs.tmp.xlsx", firstrow</span> will read the first sheet and use headers{'\n'}
|
||||
for more help, see <span {...b}>import excel</span>
|
||||
</pre>
|
||||
|
||||
17) Close the plugin:
|
||||
|
||||
```stata
|
||||
program drop cleanfile
|
||||
```
|
||||
|
||||
18) Clear the current session:
|
||||
|
||||
```stata
|
||||
clear
|
||||
```
|
||||
|
||||
<p>19) In the result of Step 16, click the link on <code><span {...b}>import
|
||||
excel "sheetjs.tmp.xlsx", firstrow</span></code></p>
|
||||
|
||||
Alternatively, manually type the command:
|
||||
|
||||
```stata
|
||||
import excel "sheetjs.tmp.xlsx", firstrow
|
||||
```
|
||||
|
||||
The output will show the import result:
|
||||

||||
<pre>
|
||||
<b>. import excel "sheetjs.tmp.xlsx", firstrow</b>{'\n'}
|
||||
(2 vars, 5 obs)

||||

#### Some decimal values are rounded
|
||||
|
||||
Excel appears to round values in certain cases. It is suspected that the XLSX
|
||||
parser handles 15 decimal digits of precision. This results in inaccuracies such
|
||||
as `7581185.559999999` rounding to `7581185.56` and `7581185.5599999903`
|
||||
rounding to `7581185.55999999`.
|
||||
|
||||
See [Issue 3003](https://git.sheetjs.com/sheetjs/sheetjs/issues/3003) in the
|
||||
main SheetJS CE repo for details.
