Importing a file means bringing its contents into a program so they can be used there. The term has two common meanings: a program may load code as a module, or an application may read data into a table, document, or workspace. The steps depend on the software, file type, and intended result.
What does “import a file” mean?
Importing is not one universal operation. In programming, it usually means making code from another module available to a program. In a data or productivity application, it usually means reading an external file and converting its contents into a structure the application can use.
| Meaning | What is brought in | Where it goes | What affects the result |
|---|---|---|---|
| Code or module import | Code and its definitions | A language’s module system or namespace | Language rules, module location, and when loading occurs |
| Data-file import | Records or other file contents | A table, document, or application workspace | File format, headers, separators, layout, and destination |
Importing code as a module
A code import asks a language runtime to locate a module and make its code available. The Python 3.14.8 reference describes importing as the way “Python code in one module gains access to the code in another module” (Python import system documentation). It is not simply copying a file into a document: the runtime must resolve the module according to the language’s rules.

Importing a Python file can also execute its top-level code, making its definitions available through the module; the Wellesley College CS111 glossary notes this behavior in its explanation of importing (Wellesley CS111 glossary). That means importing a module can have effects beyond making functions or classes available if the file performs actions when it loads.
JavaScript has static and dynamic imports
JavaScript’s static import declarations are handled as part of module loading. The dynamic import() expression loads an ECMAScript module asynchronously and on demand, resolving to a module namespace object if loading and evaluation succeed; failures reject the returned promise. MDN describes dynamic import as useful for conditional or on-demand loading, constructed module specifiers, or use from a non-module environment, while static imports can support static analysis and tree shaking (MDN Web Docs: import()).
Importing data into an application
A data import reads an external file and maps its contents into the application’s own structure. For example, JMP 19.2 documentation says JMP converts supported non-JMP files, including Excel and text files, into data tables. Its listed examples include Excel, text, CSV, JSL, DAT, TSV, and JRN files. Recognition can depend on the operating system and filename extension (JMP 19.2: Import Data).
Applications may ask how the data is arranged before importing it. Alpha Anywhere’s import guide describes choosing a file type, configuring field names, selecting a destination table, setting delimiters or record structure, and deciding how to handle duplicate records (Alpha Anywhere import operations).

Settings determine how records are read
A delimiter separates fields in a delimited file; a header row may identify the fields; and a destination setting determines where records are stored. Fixed-width files require the application to interpret fields by position rather than by separators. Alpha Anywhere warns that incorrect assumptions about a fixed-width file’s structure can produce an incorrect import; field offsets and widths may need to be specified manually.

A general data-import workflow
These steps describe the usual decisions, not a universal set of buttons. Menu names and available formats vary by application.
- Open the application’s import command or file-opening workflow.
- Select a supported source file and, if prompted, identify its format.
- Confirm how the application should interpret the contents, including headers, delimiters, field widths, or record layout where relevant.
- Choose the destination, such as a new or existing table or workspace.
- Review the imported result and check for missing, shifted, duplicated, or incorrectly parsed values.
What information is needed for exact instructions?
To get steps that match your situation, specify the application or programming language, the file type, and what you want to happen to its contents. For example, importing a CSV into a spreadsheet is a data-import task; importing a Python module into a program is a code-import task. Their controls and rules are different, so one product’s instructions should not be treated as universal. For current, product-specific steps, consult that software’s official help and verify its supported formats for your version.
