This discussion focuses on the Stata DTA codec. For integrating SheetJS in a
|
|
|
|
|
Stata extension, there is a [dedicated demo](/docs/demos/extensions/stata).
|

|
[Stata](https://stata.com/) is a statistical software package. Econometricians
|
|
|
|
|
and social scientists have used Stata for data processing and statistical
|
|
|
|
|
analysis. Many legacy datasets are only available in Stata DTA data files.
|
|
|
|
|
|
|
|
|
|
The SheetJS DTA Codec enables websites and automated data pipelines to integrate
|
|
|
|
|
data from DTA files.
|
|
|
|
|
|
|
|
|
|
Source code and project documentation are hosted on the SheetJS git server at
|
|
|
|
|
<https://git.sheetjs.com/sheetjs/sheetjs/src/branch/master/packages/dta>
|
|
|
|
|
|
|
|
|
|
:::caution DTA support is considered experimental.
|
|
|
|
|
|
|
|
|
|
Great open source software grows with user tests and reports. Issues should be
|
|
|
|
|
reported to [the issue tracker](https://git.sheetjs.com/sheetjs/sheetjs/issues).

## Live Demo
|
|
|
|
|
|
|
|
|
|
This demo fetches a [sample DTA file](pathname:///dta/pres.dta), parses the data
|
|
|
|
|
using the SheetJS DTA Codec and displays the data in an HTML table using the
|
|
|
|
|
`sheet_to_html` method[^1].

|
|

The file input element can be used to parse a file on your computer.
