Answer

To convert text that looks like numbers into real numeric values in Excel, you can use functions (VALUE, NUMBERVALUE), simple math operations (multiply by 1 / add 0), Paste Special, Text to Columns, Error Checking, or VBA for large/recurring tasks. Below are the major methods, troubleshooting tips, and best practices.

Using the VALUE Function

·         What it does: Converts text in a recognized numeric, date, or time format into a number.

·         How to use: =VALUE(A1) where A1 contains the text-formatted number.

Multiplying by 1 or Adding 0

·         Quick helper-column method: In a helper column enter =A1*1 or =A1+0.

·         Then: Copy the formula down, copy the results, and Paste Special → Values over the original if you want to replace them.

Using Paste Special (Multiply)

1.      Type 1 in any empty cell.

2.      Copy that cell (Ctrl+C / Cmd+C).

3.      Select the text-number cells.

4.      Right-click → Paste Special → Operation: Multiply → OK.
This forces Excel to convert text to numbers.

Text to Columns Method

·         When to use: Fast one-step conversion when numbers are in a single column.

·         How to use: Select the column → Data tab → Text to Columns → Click Finish immediately. (Does not split data if no delimiter is found.)

Using the Error Checking Option

·         Excel displays a green triangle for numbers stored as text.

·         Click the cell(s) → click the error icon → choose Convert to Number.

·         Works well for small selections or highlighted ranges.

NUMBERVALUE Function

·         Handles locale separators: =NUMBERVALUE(A1, decimal_separator, group_separator)

·         Example: =NUMBERVALUE(A1, ",", ".") if the decimal separator is a comma.

Removing Non-Numeric Characters before Conversion

·         Clean spaces / non-printables: =CLEAN(TRIM(A1))

·         Remove specific characters (e.g., $): =SUBSTITUTE(A1,"$","") then convert.

·         Clean first, then use VALUE or math conversion.

Handling Dates Stored as Text

·         Use =DATEVALUE(A1) to convert text dates into Excel serial date numbers.

·         After conversion, format the cell as a Date to display correctly.

Converting Multiple Columns / Bulk Fixes

·         Remove hidden spaces: Select columns → Ctrl+H (Cmd+H) → Find what: single space → Replace with: (leave blank) → Replace All.

·         For large/recurring conversions, consider a macro (see VBA below).

VBA Method for Large Datasets

·         Quick macro:

Sub ConvertTextToNumber()

    Selection.Value = Selection.Value

End Sub

·         Select the cells to convert, run the macro. Use when you need to repeat conversions across many ranges.

Identifying Text Numbers

·         Alignment: Text aligns left by default, numbers align right.

·         Functions: =ISTEXT(A1) returns TRUE for text values.

·         Counts: COUNT ignores text; COUNTA counts non-empty cells.

Common Conversion Issues

·         Leading apostrophes (') — remove using Find & Replace (find: ', replace: empty) or use error-check Convert to Number.

·         Scientific notation for long numbers — format cells as Number (0 decimal places) before entering or store as Text with custom format if needed.

·         Array size mismatches — when using formulas across ranges, ensure dimensions match.

Preserving Leading Zeros

·         Converting to number will strip leading zeros. To preserve codes like 0012:

o    Keep as Text format, or

o    Use a Custom number format like "0000" (for fixed width), or

o    Store the original text separately before converting.

Best Practices

·         Always back up or copy the original data before bulk conversions.

·         Clean data first (TRIM, CLEAN, SUBSTITUTE) to remove stray characters.

·         Use VALUE or math operations for quick one-off fixes; use NUMBERVALUE for locale-aware conversions.

·         Prefer Text to Columns or Paste Special for fast, simple conversions.

·         Use VBA for repeatable, large-scale operations.

·         Verify conversion by checking alignment, ISTEXT, or running SUM/AVERAGE to ensure numeric behavior.
