About
Data portability remains a cornerstone of modern system interoperability. This tool transforms raw text-based data streams into structured spreadsheet formats compatible with major office software. Accuracy in this conversion process is paramount. Misinterpreted delimiters or encoding errors can corrupt financial records or database exports. Engineers and data analysts frequently encounter scenarios where automated systems output raw CSV logs that require manual inspection. This converter parses the input stream byte-by-byte to respect quoted strings and special characters before reconstructing the dataset into an Excel-friendly structure. It operates entirely on the client side to ensure sensitive data never leaves your local environment.
Formulas
While file conversion is algorithmic rather than mathematical, understanding the data volume is useful for estimation. The approximate size of a resulting raw dataset can be modeled by summing the byte length of all cells plus row overhead.
Where R is the row count and C is the column count. The factor 1 accounts for the delimiter. Excel files will include additional XML markup overhead.
