TelaViewerTechnical sheet and supported formats

BusinessVersion 1.3.1
October 2026
TELANODE SAS

TelaViewer reads, without the original software, the files your teams receive, archive or inherit: documents, data, archives, plans, emails, applications, accounting entries and bank statements. Your specialised licences stay reserved for those who create or edit the documents.

TypePortable native C++ application: a single executable file, under 15 MB, with no DLL, OCX, .so or runtime to install (Visual C++, .NET, Java)
SystemsWindows 10 and Windows 11, 64-bit
RequirementsMicrosoft Edge WebView2 engine (included in Windows 11; offline installer available from Microsoft)
DeploymentNo installation, no administrator rights; runs from a folder, a share or a USB stick
NetworkNo connection, no sending of files or statistics, no account. The required diagnostic data of the WebView2 engine is governed by Windows settings
FilesRead-only: displayed files are never modified; protected files are decrypted in memory, passwords never saved
SecurityNo program, macro or script contained in a file is ever run; attachments, shortcuts and programs are shown as information sheets
IntegrationFile associations and “Send to” menu as the user chooses; the default program is never changed; command-line registration for deployments (TelaViewer.exe /register, /unregister)
UseNavigation pane (favourites, recent folders, disks and USB sticks), search in the page and across a whole workbook, printing with preview, light or dark theme, automatic reload of a modified file, last 20 opened files; French interface
Large filesMulti-GB logs and text files read in parts, logs from the end first; a one-million-line FEC opens in about two seconds
DatabasesRead directly from the file: no ODBC, no driver, no Access engine (Jet / ACE), no server
Accounting and bankingAccounting entries and bank files recognised from their content, whatever the extension; trial balance, journals and balances recalculated; indicative checks (balance, numbering, dates, FEC columns, IBAN, declared totals)Pro
ExportsProUTF-8 CSV of tables, entries and statements, ready for Excel (databases: “;” separator and decimal comma, or international format); database structure exportable to Markdown or to an HTML page for Word; entries in FEC format (18 columns, tab-separated)
