Your CSV files stay on your device

The browser reads and compares selected files locally. File names, headers, keys, values, and generated reports are not sent to ExportDelta. Closing the page clears the comparison. Downloads are saved by your browser; store and share them carefully.

Minimal usage counting

The application sends a fixed event name and a fixed source category (direct, DevPages, Ignlab, AwesomeCSV, GitHub, or search) when a page is opened, a demo or comparison finishes, a validation error occurs, a report is exported, or someone expresses interest in automation or opens its checkout. We store daily totals by event and source category, with no account, email, visitor identifier, cookie, filename, or file contents. The source category is derived in your browser from a recognized campaign label or referring site. We do not send or store the referring URL, search query, or other URL parameters; unknown sources are grouped with direct traffic. These are raw event counts that can include repeated actions or automated traffic. They are not unique visitors, verified buying interest, or proof of sales. The hosting provider may process IP addresses and technical request information to deliver and protect the site under its own policies.

Limits and interpretation

• UTF-8 CSVs only, with an optional BOM. Maximum 10 MiB, 100,000 records, 500 columns, and 500,000 cells (including headers) per file. Comparisons stop above 100,000 changed fields.
• Choose the delimiter before opening a file. Comma, semicolon, tab, and pipe are supported.
• Every file needs distinct, non-empty column headers. Keys must be present in both files, non-empty, and unique after normalization.
• Values are compared as text. There is no numeric tolerance, date conversion, or automatic data repair. Whitespace and letter case matter unless you choose otherwise.
• Column order and record order are ignored. Added or removed columns are reported even when ignored for value comparison.
• The on-screen table shows up to 100 changed fields. Downloads contain the full report.
• CSV report cells that could be interpreted as spreadsheet formulas are prefixed with an apostrophe. JSON preserves exact values. HTML reports escape untrusted text.

Automation pack

The automation pack is sold and delivered through Gumroad. Its product page provides the current price, requirements, license and seller contact. Gumroad processes purchase contact and payment information under its own policies; ExportDelta does not receive your card details or CSV files. Review the final price, currency and any taxes at checkout. For seller support, contact hello@realmajed.com or reply to your purchase receipt.

ExportDelta is a comparison aid. Review reports against the source files before importing or applying changes.
