Changing tools is mostly a question of data: what you can get out of the old one, in what form, and how to check that nothing was lost on the way. This guide targets no particular service. It always follows the same five steps, and it says what we could verify in each service's official help as of 19 October 2026, and what we did not find.
One principle first: the most reliable source is almost always your bank or your broker, not the app in between. A bank statement is the original document; an app's export is a copy, sometimes a partial one.
Step 1: know what you want to bring over
Three kinds of data, which do not come from the same place:
- transactions (what went in and out of your accounts): they feed the budget;
- positions (what you hold: shares, funds, accounts, with their value): they feed net worth;
- order history (buys and sells): it lets the cost of each line be worked out.
Many apps export transactions. Few export positions. Check that first, before giving up a tool.
Step 2: export, with what actually exists
What the official help pages document, without assuming what is not written:
- Finary: a CSV export of the transaction history of the investment tracker (Transactions tab, "Export transactions", with a date range). We found no export of holdings in the official help.
- Bankin': an export of the bank history, reserved for the paid Plus and Pro plans (Profile, "Data export", period and accounts of your choice), sent by email in Excel and CSV. The history available depends on what each bank makes available.
- YNAB: "Export Plan" from the web app, which produces two CSV files (the plan, and the transaction history).
- Boursobank: a CSV export of an account's movements once the period is chosen, and PDF statements in the Documents area.
- Interactive Brokers: "Flex Query" reports (CSV, XML) for transactions and orders, and downloadable statements.
- Binance: a transaction-history export (Assets, History), with download links that expire after seven days.
- Fortuneo: we found no documented export. PDF statements remain the safe route.
For any other app the method is the same: search its help centre for "export", and note the stated limits (duration, paid plan, format). If the help says nothing, do not assume: ask the publisher, or start again from your bank's statements.
Step 3: prepare the files
- One file per account, clearly named ("PEA-2025.csv").
- Do not alter the columns: IgniFI recognises the usual headers of French banks, including semicolon separators and decimal commas. A file opened and re-saved by a spreadsheet sometimes changes its encoding or its dates.
- Import the oldest first if you have several periods: the history is rebuilt in order.
Step 4: mask what does not need to travel
A CSV or Excel file is read in your browser. A PDF or a screenshot, on the other hand, is sent to Google (Gemini) to extract its lines, only if you choose that route (IgniFI's privacy policy spells out what is transmitted, and IgniFI does not keep the document). Before sending a PDF or an image:
- mask full account numbers and IBANs if they are not needed;
- mask the names of third parties who have no reason to appear;
- keep only the pages you need.
Figures and dates must stay legible: a blurred or too-small screenshot is refused, because a guessed figure would be worse than a missing one.
Step 5: import, then check
- Transactions go to Budget; positions and values to Import; orders to the account concerned.
- On the review screen, compare the total with the one printed on your statement. IgniFI itself reconciles the imported lines with the balance when it can read one, and flags a gap; settle a gap before going on, not after.
- Check three things by eye: the first and last dates, the number of lines, and a purchase you know by heart.
- Keep the old tool open for a week while you cross-check.
Afterwards: delete what no longer has a use
An export contains all your transactions. Once the import is checked:
- delete the files from your Downloads folder, then empty the trash;
- delete the attachment from your mailbox, and from the "Sent" folder if you emailed it to yourself;
- delete the copy in any synced cloud folder;
- if you are leaving a service, ask it to delete your account: that right is yours (GDPR, Article 17).
IgniFI connects to no bank: it only receives the files you give it, which is what makes this clean-up list complete.
