Abstract: A computer-implemented method for editing a formula includes receiving a text string including formula information. The method further includes parsing the received text string and analyzing the parsed text string for a formula and formula errors while the text string is being received. In response to a formula error being detected in the analyzed text string, the method can include generating a message pertaining to the formula error. In response to a formula detected in the analyzed text string, the method can include calculating at least one sub-value for the formula and generating a message pertaining to the at least one sub-value of the formula.
