Extracting Numbers from Strings in Excel

Using Built-in Functions

Excel users can extract numbers from strings using functions like LEFT, MID, RIGHT, FIND, and LEN. The RIGHT function is ideal for numbers at the end of a string, while MID, SUBSTITUTE, and SUMPRODUCT are suitable for numbers at any position. Knowledge of these functions is essential for working with alpha-numeric strings.

Advanced Excel Formula for Number Extraction

For mixed strings, the formula =IF(SUM(LEN(A2)-LEN(SUBSTITUTE(A2, "0","1","2","3","4","5","6","7","8","9", "")))>0 can be combined with the TEXTJOIN function in Excel 365 to Excel 2019 to extract numerical values. Regular expressions, available through functions like RegExpExtract in the Ultimate Suite, offer pattern-based extraction.

Substring Functions and Tools

Excel's Substring functions, such as LEFT, RIGHT, and MID, can be used to extract numbers. The Extract tool in the Ultimate Suite simplifies this process with a mouse click. Excel versions lacking the TEXTSPLIT function can use regular expressions for similar functionality.

Number Extraction with Excel Formulas

The formula =LEFT(A1, SEARCH("-", A1) - 1) & "-" & RIGHT(A1, LEN(A1) - SEARCH("-", A1)) demonstrates how to extract numbers separated by a hyphen, utilizing LEFT, RIGHT, and SEARCH functions. This formula assumes a basic understanding of Excel formulas and is useful for users at all levels.

Utilizing Excel Functions for Specific Cases

TEXTBEFORE and TEXTAFTER functions are helpful for extracting numbers around specific symbols. The SEARCH function finds the position of text, aiding in the extraction process with MID. The ISNUMBER function checks for numeric values, supporting complex extraction tasks.

Common Use Cases

• 
  Extracting invoice numbers from a mixed text and number column
• 
  Isolating student ID numbers from a list of usernames
• 
  Compiling phone numbers from a directory with additional text
• 
  Calculating sums from strings that contain both text and numerical values
• 
  Sorting entries based on numerical values extracted from product codes

Excel vs. Sourcetable: A Comparative Analysis

Excel is a traditional spreadsheet tool known for its robust functionality and widespread use in data analysis. Sourcetable, on the other hand, is a modern spreadsheet solution designed to integrate various data sources seamlessly, providing a unified querying interface.

Sourcetable distinguishes itself with its AI copilot feature, which aids users in formula creation and template generation. This AI-driven assistance contrasts with Excel's manual approach, positioning Sourcetable as a more intuitive option for spreadsheet interactions.

While Excel requires expertise for complex tasks, Sourcetable simplifies the process with its chat interface, making advanced operations accessible to users without extensive technical knowledge. This ease of use is a key selling point for Sourcetable against the traditional Excel experience.

The choice between Excel and Sourcetable may hinge on the user's need for advanced data integration and AI assistance versus the familiarity and extensive capabilities of the established Excel platform.
