When to use an online tool instead of Excel formulas

If you open the same file weekly to run the same pivot table, an online tool saves the steps and repeats them on upload. If the file comes from someone else and has inconsistent formatting, automated cleaning is faster than manual fixes. If you need to share results with people who do not have Excel, a web link to a live report works where emailing a .xlsx does not. Free accounts handle typical spreadsheets; paid plans unlock automation for recurring analysis. Start with a free account to test your file, then upgrade when you need size or scheduling.

Pricing and how to start

Free accounts handle files under 10,000 rows and 50 columns with instant analysis and browser-based reports. Paid plans start at $9 a month and add credits, larger files and more files at once; dashboards can refresh from a connected Google Sheet. Sign up with your work email, upload a file, and see results in under a minute. Cancel anytime; no contract required. Payment is by credit card; invoicing is available for annual plans.

Common questions

Does the tool work with .xlsx and .xls files?

Yes. Upload any Excel format including .xlsx, .xls, and .xlsm. Macros are ignored but all data and formatting are read.

What does it cost?

You can try it free without an account, and the free plan includes credits every month. Paid plans add more credits and seats; every feature is on every plan. See the pricing page for current prices.

Is my data sent to a server or does it stay local?

The file is not uploaded to a server unless you explicitly save a report or schedule a refresh, and then it is encrypted at rest.

Can it handle files with multiple sheets?

Yes. The tool reads every sheet, lets you pick which to analyze, and can join data across sheets if they share a common column like Invoice Number or Date.

What kind of analysis does it generate automatically?

Summary statistics for numeric columns, frequency counts for text, duplicate detection, blank-cell reports, trend identification for date series, and outlier flagging for amounts.

Try it with your own file

DataMimi reads the file you actually have — merged cells, headers below row one, totals pasted at the bottom — and shows which rows and columns every number came from.
