Sifar Data

Quick answers

1. Can I open a CSV that is too big for Excel?

   Yes. Excel stops at 1,048,576 rows and silently drops anything past that, and even smaller files can freeze or crash with many columns. Sifar Data opens CSV files with millions of rows and lets you filter, summarize, and chart them without the spreadsheet choking, with no upload and no waiting since the file is read on your computer.

2. How is this different from asking ChatGPT or another AI to analyze my file?

   General AI assistants require uploading your entire file to their servers with upload caps well below real data exports, causing slow uploads every time and often failing for large files. Sifar Data keeps the file on your machine running analysis locally, with no upload, no size ceiling, and your raw data never leaving your laptop. The AI only receives column names, types, sample rows, and query result summaries, or no rows at all in strict privacy mode.

3. How large can my files be?

   Most modern laptops handle CSV files up to 5 GB comfortably. Files are streamed and parsed in chunks to keep memory use predictable, making a 10-million-row file normal on a typical machine.

4. Do I need to know SQL or how to code?

   No. You ask questions in plain English, like "which region grew the most last quarter?" or "show me orders over 500 dollars from repeat customers," and Sifar Data writes and runs the query for you. It also shows you the SQL it used, so if you are curious or want to learn, it is right there — but you never have to write it yourself.

5. Can I analyze several CSV files at once?

   Yes. You can open multiple files and ask questions that span them — for example joining an orders file to a customers file to a regions file — without setting up VLOOKUPs or a database. Sifar Data handles the join and gives you back a single answer.
