How to open camt.053 and MT940 bank statement files in Excel or CSV
camt.053, camt.052 and camt.054 are ISO 20022 XML files; MT940 and MT942 are SWIFT text files made of tagged lines such as :60F:, :61:, :86: and :62F:. Neither opens as a table when you double-click it. Your online banking may offer the same account as CSV or Excel, and Excel can import camt XML if you reshape it yourself. Camtwright reads all five formats into one table, checks every statement's balances to the cent and exports to Excel or CSV.
Read the guide →How to convert a PDF bank statement to Excel, CSV or QBO
First see whether your online banking offers the same transactions as CSV, QBO or OFX: then nothing needs converting. With only the PDF, QuickBooks Online can read English statements itself, and Excel with a Microsoft 365 subscription on Windows can pull tables out of a PDF, but copied or extracted tables often need fixing. Ledgerwright reads PDF statements on your PC, checks that the balances add up and exports Excel, CSV, QBO, OFX, QFX or QIF.
Read the guide →How to open a .pages, .numbers or .key file on Windows (and convert it to Word, Excel, PowerPoint or PDF)
The simplest fix is to ask the sender to export the file from Pages, Numbers or Keynote as Word, Excel, PowerPoint or PDF. On your own Windows PC, you can sign in to iCloud.com with an Apple Account, upload the file and download a Word, Excel or PowerPoint copy, or open it in the free LibreOffice and save it in a Microsoft format. Foliowright ($6.99) shows the preview stored in the file at once, and converts single files or whole folders with LibreOffice, without uploading anything.
Read the guide →How to open InfoPath forms (.xml) and templates (.xsn) without InfoPath
InfoPath 2013 is the last version of InfoPath, and Microsoft's support for it ended on 14 July 2026, the same day as for InfoPath Forms Services in SharePoint. An archived form is an XML file: a browser or text editor shows its raw data, but not the form, because the layout lives in its .xsn template. To read the forms as forms again and convert them to PDF, Word or Excel, use an InfoPath that is still installed, or Formwright ($39.99), which shows each form through its own template on Windows without InfoPath.
Read the guide →How to open an .mpp file without Microsoft Project
Microsoft says Project has no viewer program for computers without Project, so Windows cannot open an .mpp file by itself. The simplest route is to ask the sender to save the plan from Project as PDF, or as XML for other programs. To open the .mpp yourself, use the free, open-source ProjectLibre, or Ganttwright ($16.99, Microsoft Store), which shows the Gantt chart, prints it, saves it as PDF and exports the tables for Excel without changing the plan.
Read the guide →Microsoft Publisher end of support: how to open and convert your .pub files
Microsoft 365 removed Publisher from 1 October 2026, and support for the one-time-purchase Publisher ended on 13 October 2026. Your .pub files are untouched. An installed Publisher still opens them. Without it, open them in the free LibreOffice Draw, or convert whole folders to PDF and PNG with LibreOffice's command line or PUB Lifeboat.
Read the guide →How to open a PST or OST file without Outlook
A .pst file is an Outlook Data File. Classic Outlook opens it with File, Open & Export, Open Outlook Data File, and new Outlook for Windows can open one only when classic Outlook is installed too and the account has Microsoft 365. An .ost is Outlook's offline copy of a mailbox on a mail server, and Microsoft says it cannot be moved to another computer. On a PC without Outlook, Inboxwright opens both, read-only, and exports mail, contacts and calendars.
Read the guide →How to open and read your Skype chat history export (.tar and messages.json)
Skype closed on 5 May 2025, and Microsoft's pages give 15 June 2026 as the last day to request an export. If you downloaded one, it is a .tar file, and your messages are in messages.json inside it. Windows can unpack it with its tar command and Edge can show the JSON, but that is data, not a chat you can read. Chatwright opens the .tar as it is and shows each conversation as a chat, with the photos in place.
Read the guide →Why did my PC crash? How to find the cause of a blue screen from the minidump (.dmp) file
After a blue screen, Windows writes the stop code to the System event log and, depending on its settings, saves a crash dump: small ones in `%SystemRoot%\Minidump`, larger ones as `%SystemRoot%\MEMORY.DMP`. Microsoft's free WinDbg debugger reads the dump with `!analyze -v`, but it is a developer tool and the output is technical. Crashwright reads the same files offline and explains in plain words which driver is most likely involved, how sure that is and what to try. Neither can promise a diagnosis: some crashes leave no clear trace.
Read the guide →Steps Recorder (psr.exe) is deprecated: what to use instead to record steps with screenshots
Microsoft no longer updates Steps Recorder (psr.exe) and says it will be removed in a future release of Windows; since a February 2024 Windows 11 update it shows a banner about this. The replacements Microsoft suggests, Snipping Tool, Xbox Game Bar and Clipchamp, record the screen as video, not as numbered steps. If you need a written how-to with a screenshot for every click, Stepwright records that on your PC and exports it to Word, PDF, HTML or Markdown.
Read the guide →How to open a CSV file that is too big for Excel, and Parquet files
An Excel worksheet holds at most 1,048,576 rows, so Excel loads only part of a bigger CSV file and warns that saving would lose the rest. To use every row, load the file into a PivotTable with Excel's Get Data, query it with the free DuckDB command line, or split it into parts. To browse, sort, filter and query millions of rows of CSV or Parquet in a window, offline, there is Tablewright ($9.99, Microsoft Store).
