Grab the Montant, Destinataire, and Date from Any Lydia Screenshot
France's most popular P2P payment app uses French labels (Montant, Destinataire, Date), a decimal comma (12,50€), and DD/MM/YYYY dates — all of which break standard OCR trained on English formats. Semantic extraction reads by label meaning, not position — in under 10 seconds per screenshot.

What You Can Pull from a Lydia Screenshot
A Lydia screen carries four fields in French labels. With Custom Column Extraction, you name the columns; the AI reads each value by its French label context, not pixel position.
The amount in euros, with a decimal comma (12,50€ not 12.50). On personal transfers, this is the full amount. On cagnotte contributions, it's what you added to the pool — not the total balance.
The recipient, shown as a Lydia username plus legal name. For cagnotte contributions, the label is replaced by the cagnotte's name — the AI reads whichever is present.
Displayed in DD/MM/YYYY — the day and month are reversed compared to US MM/DD/YYYY, which can misalign month-first spreadsheets.
Free-text field — "dîner du 14 juillet", "cadeau commun pour Marie". Unstructured but carries the real context.
French Labels, French Formats — and a Cagnotte That Changes What "Amount" Means
Lydia screenshots carry three challenges no English-language tool accounts for: a decimal comma (12,50€), DD/MM/YYYY dates, and a cagnotte feature that redefines what "Montant" means.
The Decimal Comma Problem
Lydia displays 12,50€ — not 12.50. Standard OCR sees the comma as a separator, splitting the value or dropping cents. A French user on Reddit noted that "Lydia ne propose pas d'export automatique des transactions" — users screenshot, and the comma trips up every standard tool.
Cagnotte: Whose Amount Is It?
Lydia's cagnotte lets multiple people contribute to a shared pot. A screenshot shows your contribution amount and the cagnotte's total. Without knowing which is which, a template tool assigns the wrong value. The two figures can differ by an order of magnitude.
The Post-Acquisition UI Split
BNP Paribas acquired Lydia in 2023; the UI has been in transition since. The 2024 spin-off of banking into Sumeria created a fork — the original payment app still exists but its layout shifted. Users searching French forums may be working with either version. Template-based extraction breaks between them; semantic extraction does not.
Comma-Aware Extraction
The AI reads the Montant label alongside the value — it understands "12,50" is a single amount with a decimal comma, not two tokens. If your spreadsheet expects period decimals, the post-processing layer converts commas during export — no manual find-and-replace.
Label-Context Disambiguation
Define a Montant column and the AI reads the value beside the "Montant" label. On a cagnotte screen, the contribution is labelled "Montant" while the total is "Cagnotte" or "Total de la cagnotte." The AI picks the right one by French label context, not by guessing which figure is bigger.
Layout-Independent Across Versions
Because the AI reads by meaning rather than pixel coordinates, a Lydia screenshot from 2022 produces the same output as one from 2026. The label-to-field relationship — Montant above the amount, Destinataire beside the recipient — has remained stable even as button styles and spacing evolved.
From a Lydia Confirmation Screen to a Usable Spreadsheet Row
If you're logging Lydia payments — for shared household expense tracking, group trip cost splitting, or year-end budgeting — here's what happens when you drop a screenshot into the tool.
Upload the Lydia Screenshot
Upload a Lydia payment confirmation screen — either a personal transfer showing Montant, Destinataire, and Date, or a cagnotte contribution showing your contribution amount alongside the pool's total. The confirmation card is high-contrast machine-rendered text, well-suited for extraction. The AI reads the French labels to determine what each figure represents.
Name the Columns
Define your column headers: Montant, Destinataire, Date, Description. The AI reads the value beside each French label — not by pixel position. The decimal comma (12,50€) is preserved as-is. If your spreadsheet expects period decimals, the post-processing layer converts the comma during export. Add a Computed Column like Cagnotte (Montant / Total) to flag whether a row is a personal transfer or a pool contribution.
Export the Row
The output lands as a single spreadsheet row — Montant, Destinataire, Date, Description. Export to Excel, CSV, or push directly into Google Sheets via the add-on. One screenshot becomes one row, each field in its correct column, with the French formatting preserved. Batch Lydia screenshots alongside Revolut, PayPal, and Venmo — the same column definitions work across all payment apps.
When Lydia Screenshot Extraction Works Best — and When It Doesn't
When It Works Best
Clear transaction confirmation screenshots. The Lydia payment card shows Montant, Destinataire, Date, and Description in high-contrast machine-rendered French text — well-suited for semantic extraction.
Batch cross-platform processing with other payment apps. One column set extracts from Lydia alongside Revolut, PayPal, Venmo, and other payment screenshots — French labels and English labels merge into one spreadsheet.
Cagnotte contribution tracking. The AI distinguishes between the contribution amount and the cagnotte total by reading French label context — ideal for group expense reconciliation.
When to Be Cautious
Sumeria banking app screenshots. The 2024 Sumeria spin-off uses a different layout and terminology — separate Lydia payment screenshots from Sumeria banking screenshots in different batches.
Heavily cropped or low-resolution images. If the screenshot is zoomed in too tightly on the amount and cuts off the label, the AI loses the label context it needs to confirm the field identity.
Pending or unconfirmed payments. Lydia marks pending transactions with a different visual style. Wait for the status to reach "Confirmé" before extracting for permanent records.
Frequently Asked Questions
How does the tool handle the French decimal comma (12,50€) in Lydia screenshots?
The AI extracts the value as it appears on screen — 12,50€ — and preserves the original format. The tool's post-processing layer can optionally convert the comma to a decimal point (12.50) during export. This is configured per column, so you can keep the original French format for local records and convert to period format for systems that require it. The Montant column captures the full value including the comma, never splitting it into two cells.
Can I extract data from a cagnotte (group pool) contribution screenshot?
Yes. A cagnotte contribution screen shows two euro figures: the amount you personally added and the cagnotte's total balance. Define a Montant column for your contribution and a separate Cagnotte Total column if you need the pool's full balance. The AI reads the label beside each figure — "Montant" for your contribution, "Total de la cagnotte" for the pool sum — and assigns the correct value to each column. The cagnotte name appears near the top of the confirmation card, distinct from the Destinataire field on a personal transfer.
Does the 2023 BNP Paribas acquisition affect extraction accuracy on older Lydia screenshots?
No. The acquisition triggered a gradual UI evolution — the label-to-field relationships (Montant, Destinataire, Date, Description) remained consistent even as spacing and button styles changed. Because Custom Column Extraction reads by semantic meaning rather than pixel coordinates, a screenshot from 2022 produces the same output as one from the current 2026 app. The one exception is the Sumeria banking app (2024 spin-off), which uses a different layout entirely — keep Lydia payment screenshots and Sumeria banking screenshots in separate batches.
The Description field on my Lydia screenshot is in French free text — will the extraction capture it correctly?
Yes. The Description field is unstructured free text — users write anything from "dîner du 14 juillet" to "cadeau commun pour Marie" to "loyer janvier". The AI extracts the text as-is, including emoji, accented characters, and abbreviations. This field carries the real context behind the transaction — the reason that turns a montant figure into a meaningful record. The extracted text is returned as a string in the Description column, exactly as it appears on the screen.
Can I batch Lydia screenshots with Revolut and PayPal screenshots in the same export?
Yes. Define one set of column names — Montant, Destinataire, Date, Description — and the AI processes Lydia, Revolut, PayPal, and Venmo screenshots in a single batch. For Lydia, the AI reads the French labels; for Revolut, the English labels. The output is one spreadsheet with a row per screenshot, regardless of which app generated it.
