An open-source file format for spreadsheets stored in JSON.\n\n[Read the syntax standard.](SYNTAX.md)\n\n[View an example JTF file.](example.jtf)\n\nThis repository is a hybrid, it contains the standards and information on the `.jtf` file format, as well as an efficient library of tools for interacting with JTF data.\n\n[Read the wiki.](https://github.com/NotTimTam/jtf/wiki)\n\n## Why JTF?\n\nThe `.jtf` format is an attempt at bridging the gap between popular spreadsheet file formats and JavaScript. Complex libraries are generally required to parse `.xlsx` files and their equivalents for use in JavaScript. It is even harder to export content back in to those formats. Formats like `.csv` are far too rudimentary and do not support things like styling and formulas.\n\n`.jtf` data is stored in a familiar and readily accessible structure, **JSON!** Making it somewhat readable in its raw state, and requiring only a small amount of code to properly compile it into a table. `.jtf` data can be stored interchangably within JavaScript objects, `.json` files, and `.jtf` files.\n\nIt employs an `.xlsx`-based formula system and a JavaScript-friendly easy-to-use cell targeting system.\n\nThis library contains methods for validating, reading, and writing `.jtf` format files **with zero dependencies!**\n\nFor custom applications, developers looking to support `.jtf` files in their projects are encouraged to write their own code for interacting with the format.\n\nContributions to the format and codebase are also welcome. See [CONTRIBUTING.md](CONTRIBUTING.md) for more.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnottimtam%2Fjtf","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnottimtam%2Fjtf","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnottimtam%2Fjtf/lists"}
