Question 1

What does the CSV Analyzer detect?

Accepted Answer

It detects column data types (text, number, date, email, boolean), row and column counts, file encoding, delimiter type, and whether your file fits within Google Sheets' 10 million cell limit. You get a full structural overview before any processing.

Question 2

Can I analyze Excel files or only CSV?

Accepted Answer

Both CSV and Excel (.xlsx, .xls) files are supported. For Excel files with multiple sheets, the analyzer reads the first sheet. The results are identical regardless of format.

Question 3

Is my data uploaded to a server for analysis?

Accepted Answer

No. The analysis runs entirely in your browser using JavaScript. Your file never leaves your device, and no data is sent over the internet. This makes it safe for sensitive or confidential datasets.

Question 4

What is the maximum file size I can analyze?

Accepted Answer

There's no hard limit, but performance depends on your browser's available memory. Files up to 100 MB typically analyze in seconds. For very large files, the tool processes data in chunks to avoid browser freezes.

Question 5

How do I check if my CSV is compatible with Google Sheets?

Accepted Answer

Upload your file to the analyzer and it will automatically calculate total cells (rows x columns) and compare against Google Sheets' 10 million cell limit. You'll see a clear pass/fail indicator along with exact numbers.
