How do separators and formats change based on Excel’s regional settings?

Understanding Excel’s regional settings is key to ensuring your formulas and data run without errors. Depending on your operating system's location, essential aspects—such as function argument separators, numeric formats, and date structures—will change. 

Below, we explain the three elements you must keep in mind when working in your Excel workbook:

1. Argument separators: when to use a comma (,) vs. a semicolon (;)

This is the feature that affects formulas the most. Depending on your region, Excel uses a different symbol to separate the arguments within a function.

• Semicolon (;): This is the standard in most of Latin America, Spain, and Europe. It is also the specific separator we use on the Ninja Excel platform.

  • Example: =IF(A1>=7;"Pass";"Fail")

• Comma (,): This is the standard in the United States, Canada, and the UK.

  • Example: =IF(A1>=7,"Passed","Failed")

2. Decimal and thousands separator for numbers 

Regional settings also determine how numbers are read. Reversing these symbols will cause Excel to interpret a number as text, which invalidates any mathematical calculation.

On the Ninja Excel platform, we follow the USA/UK standard: commas for thousands and periods for decimals. 

Tip: If you see a number aligned to the left of a cell, Excel is reading it as text. This usually happens when you use the wrong decimal separator for your specific regional setting.

3. Date order: Writing days, months, and years

Correct date entry is critical for the system to validate your answer and for you to successfully apply date-based functions.

• US/International format: Month / Day / Year (mm/dd/yyyy).

• LATAM/ES format: Month / Day / Year (mm/dd/yyyy).

On the Ninja Excel platform, you must use the international format in the functions.
