What it does
- Reads what other tools mangle: memo fields from .fpt and .dbt, legacy code pages (OEM and Windows), DBF records marked as deleted, nested XML and JSON.
- Keeps your data intact: leading zeros, long IDs and account numbers stay text instead of turning into numbers with lost digits.
- Filters instead of formulas: conditions are written as a single line and run over the whole file, not just the first thousand rows.
- Compare two files by key: what appeared, what disappeared, what changed — down to the field.
- Tools: value checks (IBAN, card numbers, national ID and tax numbers of a dozen countries, emails, phones, ZIP codes), duplicates by fields, pivot tables, charts, color scales and icons, splitting and merging columns, saving as PDF, export to Parquet, side-by-side comparison, images and bytes from fields, .cdx index order, computed columns, splitting a file by a column, merging files of the same structure.
- Export to Excel, ODS, CSV, JSON, SQL, Markdown, HTML and DBF.
- Windows version: one file a few megabytes in size, no installation and no network — copy it to a USB stick and run it.

FAQ
Is my file really not uploaded to a server?
Right. Parsing happens in your browser, in a background thread. The page's security policy forbids sending data to third-party addresses, and you can see this in the developer tools. Turn the internet off — the app keeps working.
Do I need to install anything?
No, just open the page and drop a file on it. For use without a browser and without a network there is a Windows version — a single file that needs no installation.
How large a file can it handle?
DBF, CSV, XML, SQLite and Access files can be practically any size: they are read in pieces, not whole. JSON and Excel sheets are parsed into memory, so for them the limit is a few hundred megabytes.
How much does it cost?
The web app and the Windows version are free to use, with no registration and no time limit: viewing, filters, search, editing and most tools have no limits. Pro — $29, once, per user — lifts the limits on large exports, printing, tabs and batch conversion. Price and details.
