title: Is there a maximum number of formula fields allowed in Excel (2010)
body: <p>Im using a csv file to build some insert statements for SQL server and am trying to clean my data before it gets inserted, and am using formulas to fo it. I have around 64000 rows and about 30 columns to clean.</p>
  
  <p>Ive got most of the way through it, but now a formula to make sure telephone numbers are correct has just started to fail, and now just puts the text of the forumla into the cell, rather than the cleaned telephone number. The same forumla is working in other cells.</p>
  
  <p>Is there a limit to the number of formula you can have in a workbook or worksheet?</p>
  
  <p>I am using Excel 2010</p>
