Tidepath — local Sheets review

Review selected Google Sheets locally and create verified correction copies. Optional AI uses your own local API key.

Tidepath helps you review selected Google Sheets and create checked correction copies while keeping the originals intact. Requires a companion running on your computer. Install the companion from the linked source repository using Node 24.19.0 and npm 12.0.2, then keep its terminal open while using the extension. Installing the extension alone does not start the companion. A Google account with access to the selected spreadsheets is required for real Google data. The publisher configures Google authorization for the store package; users do not need their own OAuth client. A fictional rehearsal works without Google authorization. Choose the spreadsheets you want to review. Tidepath checks column mappings, duplicate gift and donor identifiers, conflicting records, dates, quantities, currencies and amounts. Findings show the affected source cells. You confirm mappings, inspect proposed changes and approve the exact plan before any correction workbook is created. Suspected duplicate gifts remain in the records; conflicting identities and unsupported values remain for human review. Correction copies preserve eligible data rows and number formats. They are not full workbook clones: excluded private columns and tabs, general styling, charts, comments, scripts and sharing settings are not copied. Formula-bearing workbooks can be reviewed, but this version blocks correction-copy creation for them. Source-version checks and saved operation history help you recover after an interruption. The companion processes selected data locally and saves a journal on your device. Google supplies the authorized source data and stores correction copies you approve. Known private labels are filtered, but labels cannot identify every confidential cell; exclude private counseling, health and other unsuitable confidential records before scanning. Tidepath does not monitor other websites or your browsing history. Deterministic review needs no model key. Optional AI advice requires your own OpenAI API key entered in the local terminal and approval of an exact outgoing request. Only scan issue counts and standard field categories are sent for advice, not raw cells or contact values. OpenAI API use is billed to your account. Advice cannot approve or apply corrections. See the setup guide for local installation, pairing, supported limits, journal deletion and recovery. This extension is independent of Tidepath's separate website and Google Workspace add-on.
