Three free web tools turn an MT940 file into CSV without an account: Toolsvana and CSVall convert in your browser, and OmniConvert converts on its server, free within a file size limit. Klarbon is free for the CSV too: it shows a preview, checks that the balances add up, and then writes the full file. Choose by where the file may go and how much the reconciliation matters.
Every fact about another tool comes from its own page, read on 7 November 2026. Where a page does not say something, the table says "not stated", not a guess.
How do the four converters compare?
| Toolsvana | CSVall | OmniConvert | Klarbon | |
|---|---|---|---|---|
| Cost | free (Toolsvana) | free, "unlimited conversions for personal and business use" (CSVall) | free and unlimited for files up to 5 MB; larger files 3 free conversions per day, then credit packs from $3 (OmniConvert) | free on the site for CSV and Excel; CAMT.053 and OFX cost credits by number of transactions (pricing) |
| Account | not stated | none | none | none |
| Where the file goes | stays in your browser, "not uploaded or stored" | stays on your device, "browser-only" | processed in server memory, deleted immediately after conversion | Klarbon's servers for the request; neither file nor transactions stored |
| Checks on the result | format detection and a confidence score per field | a preview table before download | not stated | opening balance plus transactions against closing balance, before download |
| Other outputs from MT940 | not stated | not stated | OFX, CAMT.053 | Excel, CAMT.053, OFX |
"Not stated" means the provider's page does not say. Klarbon's facts come from its own pages: bank statement to CSV and supported bank statement files.
When is Toolsvana the right choice?
When you want a quick CSV and the statement must stay on your computer. Toolsvana converts in the browser, says your data is not uploaded or stored, parses the standard MT940 tags including :61: and :86:, handles several statements in one file, and rates the confidence of each extracted field (Toolsvana).
When is CSVall the right choice?
When you want to adjust the columns before you download. CSVall converts in the browser, says files never leave your device and that no account is needed, shows a live preview where you can adjust dates or flip signs, and offers UTF-8 BOM and CRLF options for Excel (CSVall).
When is OmniConvert the right choice?
When you also need other bank formats or an API. OmniConvert converts on its servers, says files are processed in server memory and deleted immediately after conversion, needs no account, and lists conversions from MT940 to OFX and CAMT.053 as well as CSV. On 7 November 2026 its page said conversion is free and unlimited for files up to 5 MB, larger files get 3 free conversions per day, and credit packs start at $3 (OmniConvert).
When is Klarbon the right choice?
When the CSV goes into bookkeeping and you want proof that nothing is missing before you use it. Klarbon reads the MT940 file, shows a free preview with the account, period, balances, transaction count and the first five transactions, and compares opening balance plus transactions with the closing balance; it will not write an unreconciled statement. The full CSV and Excel are free on the site; CAMT.053 and OFX cost credits, counted by the number of transactions; see prices. MT940 input is in beta.
What no converter does for you
A CSV is only as useful as your software's import. Check the column layout, date format, decimal separator and sign convention your accounting software expects, and try a short period first. Where your bank offers CAMT.053, that file often carries more detail than MT940; see MT940 or CAMT.053.

Frequently asked questions
How do I convert MT940 to CSV for free?
Toolsvana and CSVall convert in your browser without uploading the file, and OmniConvert converts on its server, free for files within its size limit. All three need no account, according to their pages, read on 7 November 2026. Klarbon converts it free on its site too, with a balance check first, and needs no account.
What is the best bank statement converter from PDF to Excel in 2026?
If your bank offers an MT940 or CAMT.053 export, convert that instead of the PDF: the data comes straight from the bank, with no reading errors. For an MT940 file, a free browser tool such as Toolsvana or CSVall is often enough; choose Klarbon when you want a balance check before the CSV goes into bookkeeping.
Does the file leave my computer?
Toolsvana says your data is not uploaded or stored, and CSVall says files never leave your device. OmniConvert processes the file on its servers and says it is deleted immediately after conversion. Klarbon processes the statement on its servers for the request and stores neither the file nor the transactions.
How do I know the CSV has every transaction?
Compare the opening balance plus all transactions with the closing balance. Klarbon does this before download and refuses to write an unreconciled statement. Toolsvana shows a confidence score per field, and CSVall shows a preview table. A matching balance still does not prove every row is right.
