Turn Text into Phone Numbers in Excel — Top Conversion Software

• Create dictionaries for spelled numbers and keypad mapping.
• Iterate cells, normalize text, replace spelled numbers, map letters, strip non-digits, format as phone numbers.
• Optionally handle extensions and country codes.

Enable macros, sign your macro if distributing widely, and test on copies.

Top third-party tools and add-ins

Below are several categories of solutions and notable products. Choose based on volume, language needs, automation, and IT restrictions.

• Lightweight Excel add-ins

  • Add-ins that integrate directly into the ribbon and offer “Convert to Phone Number” options with customizable mapping. Good for non-technical users.

• Dedicated data-cleaning software

  • Tools like data-cleaning suites can parse natural-language numbers, handle multiple languages, and batch-process files (CSV, Excel, databases).

• CRM import utilities

  • If data is destined for a CRM, many CRM import tools include field normalization features including phone number parsing.

• Scripting platforms

  • For large-scale pipelines, use Python scripts (pandas + regex) or PowerShell alongside scheduled tasks.

(Names omitted because features and availability change frequently — see the comparison section for criteria to evaluate candidates.)

How to choose the best solution

Consider:

• Volume: manual formulas fine for tens of rows; Power Query/VBA for thousands; dedicated tools for millions.
• Language support: need spelled numbers in languages other than English?
• Mapping type: keypad mapping vs spelled-out digits.
• Automation: does it need to run automatically on new imports?
• Security/policy: can you enable macros or install third-party add-ins?
• Cost: free (formulas, Power Query, VBA) vs paid add-ins or services.

Example: Power Query M code snippet

Below is a conceptual M function to replace spelled-out English numbers and map letters to digits. Adapt and expand for more words/languages.

// Example M: normalize phone text (conceptual) (text as text) => let   lower = Text.Lower(text),   replacedWords = List.Accumulate(     { {"zero","0"},{"one","1"},{"two","2"},{"three","3"},{"four","4"},{"five","5"},       {"six","6"},{"seven","7"},{"eight","8"},{"nine","9"} },     lower,     (state, pair) => Text.Replace(state, pair{0}, pair{1})   ),   letterMap = Record.TransformFields(     Record.FromList({"2","2","2","3","3","3","4","4","4","5","5","5","6","6","6","7","7","7","7","8","8","8","9","9","9","9"},     {"a".."z"}),     {}   ),   mapped = Text.Combine(List.Transform(Text.ToList(replacedWords), each if Text.ContainsAny(_, {"0".."9"}) then _ else Record.FieldOrDefault(letterMap, _, ""))),   digitsOnly = Text.Select(mapped, {"0".."9","+"}) in   digitsOnly 

Comparison table (pros/cons)

Best practices

• Work on copies; never transform master data without backups.
• Standardize country codes early (store as +1, +44, etc.).
• Maintain a mapping table in the workbook for transparency and easy updates.
• Log transformations: original value → normalized value → final formatted number.
• Validate results against known samples and test edge cases (extensions, short codes).

Sample VBA starter (conceptual)

Sub ConvertLettersToNumbers()   Dim rng As Range, cell As Range   Set rng = Selection   Dim map As Object   Set map = CreateObject("Scripting.Dictionary")   ' keypad mapping   map.CompareMode = vbTextCompare   map.Add "a", "2": map.Add "b", "2": map.Add "c", "2"   ' ... add remaining mappings ...   For Each cell In rng     If Len(Trim(cell.Value)) > 0 Then       Dim txt As String: txt = LCase(cell.Value)       ' replace spelled numbers       txt = Replace(txt, "one", "1")       ' ... more replacements ...       Dim out As String: out = ""       Dim i As Long       For i = 1 To Len(txt)         Dim ch As String: ch = Mid(txt, i, 1)         If map.Exists(ch) Then out = out & map(ch)         If ch >= "0" And ch <= "9" Then out = out & ch       Next i       cell.Value = out     End If   Next cell End Sub 

Troubleshooting and edge cases

• If letters from other alphabets appear, consider transliteration first.
• For entries like “ext123” keep or move extension to a separate column.
• When formatting for international dialing, ensure leading zeros and plus signs are preserved where required.

Conclusion

For most users, Power Query offers the best balance of power, repeatability, and safety for converting letters to phone numbers in Excel. Use formulas or VBA for quick one-off tasks or when add-ins cannot be installed. For enterprise-level volumes or complex language needs, evaluate dedicated data-cleaning or CRM import tools. Follow best practices—backup data, keep mapping tables, and validate results.
