## ImportParser

<GenerationInfo sourceFile="packages/core/src/data-import/providers/import-parser/import-parser.ts" sourceLine="152" packageName="@vendure/core" />

Validates and parses CSV files into a data structure which can then be used to created new entities.
This is used internally by the <a href='/reference/typescript-api/import-export/importer#importer'>Importer</a>.

```ts title="Signature"
class ImportParser {
    parseProducts(input: string | Stream, mainLanguage: LanguageCode = this.configService.defaultLanguageCode) => Promise<ParseResult<ParsedProductWithVariants>>;
}
```

<div className="members-wrapper">

### parseProducts

<MemberInfo kind="method" type={`(input: string | Stream, mainLanguage: <a href='/reference/typescript-api/common/language-code#languagecode'>LanguageCode</a> = this.configService.defaultLanguageCode) => Promise&#60;<a href='/reference/typescript-api/import-export/import-parser#parseresult'>ParseResult</a>&#60;<a href='/reference/typescript-api/import-export/import-parser#parsedproductwithvariants'>ParsedProductWithVariants</a>&#62;&#62;`}   />

Parses the contents of the [product import CSV file](/guides/developer-guide/importing-data/#product-import-format) and
returns a data structure which can then be used to populate Vendure using the <a href='/reference/typescript-api/import-export/fast-importer-service#fastimporterservice'>FastImporterService</a>.
