Enable Editing


A modern code editor for Google Sheets functions and formulas.

Do you want to quickly understand and edit long and complex formulas? Do you want to write correct, succinct, efficient and powerful formulas? Do you want to build error-free and fast spreadsheets?

Functions and formulas are elementary components of spreadsheets and spreadsheet language; they are at the core of Google Sheets editing and programming. However, the current formula editing is constrained by the narrow formula bar or single cell boxes. Formula Editor provides features that existing tools don't have, and helps you to better understand, optimize, and write functions and formulas. Therefore, it assists you to build safe, neat and powerful spreadsheets.

At the moment, Formula Editor has two major functionalities, more features are coming soon:

Formula Optimization:

This feature is under development and it will be released in the future versions.

  • Formula Editor automatically identifies in your formula the part that can be improved in terms of correctness, readability or efficiency.
  • It suggests better ways to rewrite your formula, and explains to you why they are better, by texts and by videos!

Formula Formatting:

  • Formula Editor automatically formats a long and complex formula in several lines with appropriate with whitespace indentation and proper nesting.
  • Therefore, you could understand better the logic of the formula.

What's special?

For the time being, Formula Editor is the only one editor of Google Sheets functions and formulas in the Google Workplace Marketplace. Formula Editor is built by fancy technologies to enable its creative functionalities:

  1. It is our analyzer of spreadsheet files and formulas that powers Formula Editor behind the screen. We wrap the analyzer and make it a language server of Formula language that conforms to Microsoft Language Server Protocol. The advantage of this is to ensure the implementation of our language server standardized and independent of the editor.

  2. Then, we chose Monaco Editor to build the interface of Formula Editor. Monaco Editor is the code editor that powers the largely-used VS Code. It is very web-friendly, and has many advanced features that we leverage and will leverage for formula editing, such that coloring, IntelliSence, auto-complete, etc.
