Formulas & Functions

Viete automatically generates Excel formulas based on your descriptions. From simple sums to complex nested functions, the AI understands what calculations you need.

Supported Functions

VLOOKUP, HLOOKUP, INDEX, MATCH, XLOOKUP, INDIRECT, OFFSET

Logical

IF, AND, OR, NOT, IFERROR, IFS, SWITCH, CHOOSE

Text

CONCATENATE, LEFT, RIGHT, MID, LEN, TRIM, UPPER, LOWER, TEXT

Date & Time

TODAY, NOW, DATE, YEAR, MONTH, DAY, DATEDIF, NETWORKDAYS, EOMONTH

Financial

PMT, PV, FV, NPV, IRR, RATE, NPER

Describing Calculations

You don't need to know Excel syntax. Describe what you want in plain language:

You say:

"Calculate the total sales for each region"

Viete generates:

=SUMIF(Region,"East",Sales)

You say:

"Find the product name based on the product ID"

Viete generates:

=VLOOKUP(A2,Products!A:B,2,FALSE)

You say:

"Show 'Over Budget' if expenses exceed the budget, otherwise show 'On Track'"

Viete generates:

=IF(Expenses>Budget,"Over Budget","On Track")
Tip
Be specific about conditions and criteria. The more detail you provide about when and how calculations should apply, the more accurate the formulas will be.

Complex Formulas

Viete handles nested and complex formulas. Describe the logic step by step:

"Calculate the commission: 5% for sales under $10,000, 7% for sales between $10,000 and $50,000, and 10% for sales over $50,000. Handle errors if the sales value is missing."

This generates a nested formula like:

=IFERROR(IF(Sales<10000,Sales*0.05,IF(Sales<50000,Sales*0.07,Sales*0.1)),0)

Array Formulas

For advanced calculations across ranges, Viete can generate array formulas and dynamic arrays:

  • UNIQUE for extracting distinct values
  • FILTER for dynamic data filtering
  • SORT and SORTBY for sorted results
  • SEQUENCE for generating number series
  • Array calculations with SUMPRODUCT
Note
Array formulas require Excel 365 or Excel 2021 for full compatibility. Viete will use appropriate alternatives for older versions when specified.
