Notion formulas can manipulate data from relation and rollup properties, but searching within an array of related items requires a specific function called find(). Without this function, you cannot check whether a related page meets a condition or extract a value from a specific item inside the array. This article explains how the find() formula … Read more
When working with Notion databases, you may find that a formula referencing a rollup property fails to calculate correctly when the rollup itself pulls from another rollup across multiple related databases. This limitation causes frustration because you expect the formula to sum, count, or average values from a chain of relations, but it returns an … Read more
You need to calculate the next occurrence of a recurring event in a Notion database. Notion formulas do not have built-in support for recurring dates like a calendar app. This article shows how to build a formula that calculates the next occurrence date based on a start date and a recurrence interval in days. You … Read more
When you write a formula in a Notion database property and click Save, the system may refuse to save and show a generic syntax error message. The error does not tell you exactly where the mistake is located inside the formula. This happens because Notion does not highlight the faulty character or line in the … Read more
Notion formulas can sort arrays using the built-in sort() function, but the default behavior may not match your exact needs. By default, sort() arranges numbers in ascending order and text alphabetically. When you need a different order, such as sorting by a property value, date, or custom priority, you must supply a custom comparator function. … Read more
Notion formulas are powerful tools for automating calculations and data transformations across your workspace. However, many users notice that the same formula returns different results when viewed on the Notion mobile app compared to the desktop app. This inconsistency often stems from differences in how each platform handles date-time functions, locale settings, and formula evaluation … Read more
You want to generate an ICalendar RRULE string directly inside a Notion database so that exported events repeat correctly in calendar apps like Google Calendar or Outlook. Notion formulas can construct text strings but have no native RRULE builder. This article shows how to combine Notion properties and formula functions to output a valid recurrence … Read more
Notion’s contains() formula checks if one text string appears inside another. By default, this function performs a case-sensitive match, meaning it treats uppercase and lowercase letters as different characters. This behavior can cause false negatives when you need to compare text regardless of capitalization, such as matching user input, imported data, or mixed-case tags. This … Read more
You may notice that a Notion formula property returns only part of the expected text, cutting off at a specific character count. This truncation happens because Notion formulas have a hard limit on the length of the string they can output. The maximum output length for a formula property is 2,000 characters; any content beyond … Read more
You need a Notion formula that calculates how many buffer days remain between today and the next critical path milestone in your project. Many project managers track task dependencies manually, which leads to missed deadlines when one delay cascades through the schedule. A buffer days formula gives you a real-time count of slack available before … Read more
