Input Data Wildcard Alteryx
In the world of data analytics, one key challenge is dealing with large amounts of data from multiple sources. Alteryx, a leading data analytics platform, provides a powerful feature called Input Data Wildcard that simplifies the process of importing and processing multiple files with similar naming conventions. This article explores the functionality of Input Data Wildcard in Alteryx and how it can help analysts save time and effort in their data preprocessing tasks.
Key Takeaways
- Input Data Wildcard is a feature in Alteryx that allows for the import and processing of multiple files using wildcard characters.
- Using wildcard characters in file names, analysts can quickly and easily import and combine data from various sources.
- The feature provides flexibility in handling changing or expanding data sets.
- Wildcard characters include ‘?’ to match any single character and ‘*’ to match any number of characters.
In Alteryx, Input Data Wildcard allows analysts to specify a pattern of file names to import and process. This pattern can include wildcard characters such as ‘?’ to match any single character or ‘*’ to match any number of characters. For example, if you have a folder with multiple CSV files, such as “data_20190101.csv,” “data_20190201.csv,” and so on, you can use the wildcard pattern “data_*.csv” to import all these files at once. This eliminates the need to manually select each file and saves valuable time.
*Wildcard characters are powerful tools as they enable dynamic file selection and file naming patterns that may vary over time and across different sources.*
To use Input Data Wildcard in Alteryx, you simply specify the wildcard pattern in the file input tool. Alteryx will then import all the files that match the pattern and combine them into a unified dataset. Furthermore, the feature also allows for the extraction of additional metadata such as file names, creation dates, and file sizes, providing analysts with more insights into their data set.
Tables
| File Name | Creation Date | File Size (MB) |
|---|---|---|
| data_20200101.csv | 2020-01-01 | 10.2 |
| data_20200201.csv | 2020-02-01 | 8.6 |
| data_20200301.csv | 2020-03-01 | 11.8 |
*Input Data Wildcard is a powerful feature that allows analysts to easily import and process multiple files with similar naming conventions, saving time and effort.*
In addition to wildcard characters, Alteryx also supports regular expressions for even more powerful file selection patterns. This advanced functionality provides analysts with greater control and flexibility when working with complex file structures.
Example Regular Expression Pattern
data_[0-9]{6}.csv
*Regular expressions extend the power of wildcard characters and provide analysts with more precise control over file selection.*
In conclusion, Alteryx’s Input Data Wildcard feature offers a streamlined solution for importing and processing multiple files with similar naming conventions. Analysts can leverage wildcard characters and regular expressions to quickly and efficiently work with diverse data sets, saving time and improving data analysis workflows.
Common Misconceptions
Paragraph 1
One common misconception about input data wildcard in Alteryx is that it can only be used for reading multiple files with the same file extension. In reality, this wildcard tool can support a wide range of file types, including CSV, Excel, JSON, and more.
- The input data wildcard can read files of different formats.
- The wildcard is not limited to files with the same extension.
- It can be used with various file types like CSV, Excel, JSON, etc.
Paragraph 2
Another misconception is that the input data wildcard can only handle files with the same structure. However, this is not true. Alteryx’s input data wildcard allows you to read files with different structures, as long as they contain the necessary fields specified in your workflow.
- The wildcard can work with files of varying structures.
- It can handle different layouts and column names in the files.
- As long as the required fields are present, the wildcard can read the files.
Paragraph 3
One misconception is that the input data wildcard can only read files from a local directory. However, it can also be used to read files from network locations or remote servers, as long as the appropriate access permissions are granted.
- The wildcard can access files from network locations.
- It can read files from remote servers as well.
- Access permissions need to be granted for reading files from remote locations.
Paragraph 4
Some people believe that using the input data wildcard will result in slower performance compared to reading individual files separately. In fact, Alteryx’s input data wildcard combines file reading and processing, resulting in a more efficient workflow and potentially faster execution.
- The wildcard can actually result in faster workflow execution.
- It combines file reading and processing for improved efficiency.
- Using the wildcard can minimize the time needed for multiple file reads.
Paragraph 5
One common misconception is that the input data wildcard can only handle a limited number of files. However, Alteryx’s input data wildcard has a flexible implementation, allowing users to read and process a large number of files, limited only by system resources.
- The wildcard can handle a large number of files without limitation.
- It is not restricted to a specific number of files.
- The limitation is mainly dependent on the system resources available.

Frequently Asked Questions
What is an input data wildcard in Alteryx?
An input data wildcard in Alteryx is a special character or set of characters used to represent multiple files or
objects with similar names. It allows you to easily read in multiple files into your workflow without having to
specify each individual file name.
How do I use an input data wildcard in Alteryx?
To use an input data wildcard in Alteryx, you need to specify the wildcard character(s) in the file path or file
name field when configuring your input tool. Alteryx will then automatically identify and read in all the
relevant files that match the wildcard pattern.
What are some examples of input data wildcards in Alteryx?
Some examples of input data wildcards in Alteryx are:
*– Matches any character, including none or multiple characters.?– Matches any single character.[abc]– Matches any single character specified within the brackets.[a-z]– Matches any single character within the specified range.
Can I use multiple input data wildcards in a file path?
No, Alteryx does not support using multiple input data wildcards in a single file path. You can only use one
wildcard character or pattern at a time.
What is the difference between using an input data wildcard and explicitly specifying individual file names?
The main difference is that by using an input data wildcard, you can automatically read in multiple files with
similar names or patterns, saving time and effort. When explicitly specifying individual file names, you need to
manually input each file name, which can be tedious and time-consuming.
Can I use an input data wildcard with different file formats?
Yes, you can use an input data wildcard with different file formats. Alteryx does not limit the use of wildcards
based on file formats. You can use wildcards with CSV files, Excel files, text files, and more.
Does Alteryx support input data wildcards for remote file locations?
No, Alteryx does not support input data wildcards for remote file locations. The input data wildcard functionality
is limited to local file paths only.
How does Alteryx handle cases where no files match the input data wildcard pattern?
If no files match the input data wildcard pattern, Alteryx will return an error or an empty output, depending on
how your workflow is configured. It is important to ensure that your wildcard pattern matches the correct files
to avoid any issues.
Can I use regular expressions as input data wildcards in Alteryx?
No, Alteryx does not support regular expressions as input data wildcards. Alteryx uses its own syntax for
wildcard patterns, which includes using *, ?, and bracket expressions.
